CURRENT STATUS: can compile android kernel successfully, right now cant compile complete rom.
Edition: Windows 10
Version: 1607
OS Build: 14393.222
===========================================
REQUIREMENTS
===========================================
1) Windows 10 64-Bit with Anniversary Update
===========================================
Setting up ubuntu bash on windows 10
===========================================
1) open the Settings --> Update & Security --> For Developers--> enable Developer Mode
2) search for “Turn Windows Features On or Off” in cortana & hit enter
3) Enable the “Windows Subsystem for Linux (Beta)” option in the list and click “OK.” & restart your system
4) search for “bash” in cortana & hit enter
5) type "y" & hit enter
6) download of ubuntu for windows 10 will start. It will take some time depending on your internet speed. You’ll be asked to create a user account and password for use in the Bash environment. restart your system
7) search for “Bash on Ubuntu on Windows” in cortana & hit enter
8) congratulations you have successfully installed bash on windows 10
9) OPTIONAL
add bash to context menu (developer is Manouchehri)
install this reg entry,... Accept the warnings and import it.
===========================================
Setting up a Linux build environment
===========================================
1) open “Bash on Ubuntu on Windows”
Code:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install default-jdk
sudo apt-get install android-tools-adb android-tools-fastboot
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip python-networkx
===========================================
How To's
===========================================
warning 1: do not edit your linux files i.e. "C:\Users<username>\AppData\Local\lxss" in windows,... it will make the files useless in bash... never add files or edit files of linux subsystem from windows,....
Solution: copy the files out of linux sub system i.e. "lxss", edit them, then use bash to move the files back to "lxss"
---------------------------------------------------------------------
warning 2: Do not mnt and download android source,... download the source in linux subsystem (inside lxss) only...
---------------------------------------------------------------------
Problem: where are my ubuntu files
Solution: All your bash files are located in "C:\Users<username>\AppData\Local\lxss\rootfs". your home directory is located in "C:\Users<username>\AppData\Local\lxss\home"
---------------------------------------------------------------------
Problem: sudo: unable to resolve host
Solution: delete hosts file of ubuntu, it will auto generate the next time you open “Bash on Ubuntu on Windows" (C:\Users\<username>\AppData\Local\lxss\rootfs\etc\hosts)
---------------------------------------------------------------------
Problem: Java 8 doesn't install or work
Solution: know bug. use the following code. it will install java 7
Code:
sudo apt-get install default-jdk
---------------------------------------------------------------------
Problem: how to access windows files in bash
Solution: for example you want to navigate to downloads "C:\Users\<username>\Downloads"
Code:
cd /mnt/c/Users/<username>/Downloads
---------------------------------------------------------------------
Problem: repo not found or needs to be installed even after it was successful installed
Solution: use the following command
Code:
nano ~/.bashrc
add this at the end
Code:
PATH=~/bin:$PATH
press Ctrl+o & Ctrl+x
---------------------------------------------------------------------
Problem: can't mount my drive
Solution:: In order for a drive to show up under /mnt/ it must meet the following criteria:
1. The drive must be a fixed drive
2. The drive must be formatted to NTFS
---------------------------------------------------------------------
=======================================
*****still experimenting with bash, still have a few problems to successfully compile the rom,... will update if i find something
Move Home Ubuntu Directory
I can move ubuntu home directory from C to another drive?
@IacobIonut-DW
i am afraid you cant change it,.... there are duplicate files in ubuntu example lxss\text.txt & lxss Text.txt
if you try to copy the folder you will get a error message
It seems interesting I'm going to try it and will give you my feedback .
BTW , I've ubuntu installed along side with windows can I the files on ubuntu partition with the bash installed on windows ?
@LahKeda
No you can't read that drive
Nice to see that guide, great work!
But I am stuck at this point currently: stackoverflow | Bash on Ubuntu on Windows, Compile AOSP.
My strace file says about the same thing.
Did you find any solution to this?
@Spartaner25
did you try to edit files of linux or files of your build in windows???
Wow thanks!
But one question: Is it just another virtualization ? I mean is it faster than an Ubuntu installed inside a VM ?
For performance of bash on windows vs native Ubuntu read this

I did not touch any files of the linux base (lxss) in either the windows explorer or the bash and I did not modified anything inside the Windows Folder.
But I upgraded the system via apt update/upgrade which should not be destructive (I hope).
My target was a regular aosp build with the tag android-6.0.1_r58, I only changed a few linies in some files in frameworks/base via nano and added a device and kernel folder which was all done inside the bash.

Thanks for the hint, the kernel builds fine.
By the way, building CyanogenMod gets stuck here for me.
Windows Insider Preview for those in Fast Ring
Ubuntu 16.04 Arrives With New Windows 10 Build 14936
change log
I'm currently on this version with ubuntu 16.04 and it's getting better.
Currently the build (aosp and cm) ist stuck on the bison binary which is a prebuilt 32-bit ELF, which can not be executed.
It might be possible to replace the prebuilts with their 64-bit variants.
@chiragkrishna upon using
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip python-networkx
I get the following errors: Unable to locate package zip, lib32ncurses5-dev, libgl1-mesa-dev.
Edit: Fixed by removing the '\' from all lines.
does anyone know how to solve this error?
ionice: ioprio_set failed: Invalid argument
I have been able to successfully build cm-13.0 on Windows 10. I haven't been successful with cm-12.1, since it builds 32-bit binaries for the host executables for some reason.
The fixes I had to do:
Recompile flex and bison as 64-bit binaries according to the instructions in their source directory (github btongminh/android_prebuilts_misc)
Disable futexes in Art (github btongminh/android_art)
Disable v8 snapshots, since it is only possible to make snapshots for 32-bit targets on a 32-bit host (github btongminh/android_v8)
The build for Xiaomi Redmi 3 (ido) was successful, flashed it and it booted into Android Unfortunately after that the launcher kept on crashing, but is looks like I'm almost there.

How do you make a user build signed with release keys instead of a userdebug build signed with testkeys??
EDIT: Well my normal make build failed

What Java version are you using (java -v). LineageOS 14.1 requires Java 1.8.

How To Compile Rom From Source
We need following things to compile ROM from source
A Computer( Linux or Mac)
Java JDK
Some required Package for building Rom
Rules for Accessing USB devices
Choosing a Branch
Installing Java on the Machine
Here i am using Ubuntu(14.04 LTS) as a Linux machine but it should work for other Linux variant
Open a terminal and type following
sudo apt-get purge openjdk-\* icedtea-\* icedtea6-\*
This command will remove other existing openjdk installation
2. Once java is uninstalled use following command for installing correct version of java
sudo apt-get update
sudo apt-get install openjdk-s8-jdk
Check java version by typing following command
java -version
2. Installing some required packages
Type following in terminal to install some required packages
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip
3. Downloading Repo Tool and setting PATH
mkdir ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
Now open the bashrc file and so we can include the repo tool:
sudo nano ~/.bashrc
Add following in the end of the file
export PATH=~/bin:$PATH
Now we need to reload bash variables to include the new path:
source ~/.bashrc
4. Initializing a Repo client
Now we need to create a directory where our source code will be downloaded. I am creating a directory AOSP here
mkdir AOSP
cd AOSP
In the following command insert your name and email address
git config --global user.name "Your_Name"
git config --global user.email "Your_EMail"
Now care fully select your branch whether you are downloading aosp or Cyanogenmod
repo init -u https://android.googlesource.com/platform/manifest -b android-7.1.0_r7
type your desired branch name after the -b. This also applies to Cyanogenmod
5. Downloading source code
Now start downloading source code by typing following
repo sync
Note: this may take some time depending upon your internet speed and also please make sure you have enough storage
6. Configuring USB Access
type your username in following command and type enter
wget -S -O - http://source.android.com/source/51-android.rules | sed "s/<username>/$USER/" | sudo tee >/dev/null /etc/udev/rules.d/51-android.rules; sudo udevadm control --reload-rules
7. Now building Rom for your device
To build rom we need following
Device tree
Vendor tree
kernel
Finding device tree and Vendor Tree
To find your device tree search on Github or similar sources with your device code name. If you are lucky you will find it there and believe me it is the easiest way to build your rom rather than creating device tree and vendor tree from scratch
Your device tree will go on following location
device/device_manufacturer_name/device_codename
Same for vendor tree
vendor/device_manufacturer_name/device_codename
If you find device tree and vendor tree then how to download it
For device tree
git clone “Github url” -b (branch_tag) device/device_manufacturer_name/device_codename
2. For vendor tree
git clone “Github url” -b (branch_tag) vendor/device_manufacturer_name/device_codename
Note1: You may need to change some files if everything is not working or giving you some error in rom compiling. Look into output to find out error. You can use Google if you can't correct it
Note2: You may be not found your device tree and vendor tree then what to do?. You may need to create them. Please follow my guide
Creating Device tree and vendor tree from scratch
For creating device tree
http://azodik.com/how-to-create-device-tree-for-android-rom-building/
2. For creating Vendor tree
“Coming Soon”
Kernel
For kernel part if you are lucky than you can find your kernel source from Github or similar sources. If not you can use your prebuilt kernel Foolow this to extract your kernel http://azodik.com/how-to-create-device-tree-for-android-rom-building/
Kernel location
/kernel/device_manufacturer_name/device_codename
Downloading your kernel
Manually download it and extract to kernel location or use following command
git clone “Github url” kernel/device_manufacturer_name/device_codename
Note1: You can use your prebuilt kernel. To use your prebuilt kernel edit BoardConfig.mk file in your device tree.
Note2: If you created device tree from scratch following my guide. Use of prebuilt kernel set to default
How to build
Use following command for building your rom
Source build/envsetup.sh
lunch
Now select your device from menu
3. make or mka
I hope you found it usefull. Please follow my website for interesting guide. Please comment here if you face any error.

depend on rom for me los17 took almost 70gb
Hello Fellows,
with this Guide I would like to show what is necessary to do,
to get the new USB passthrough Feature,
from the Android Studio since Emulator 30.0.26 (August 16, 2020),
to work with a USB-Serial Device. Unfortunately the announcement "USB passthrough is now available"
needs to be taken literally. It means, just the passing from the host system to the gates of Android are possible.
There is no "taking it from there" implemented in Android nor the Kernel. And this is what this Guide is all about.
Inspired by Alabate and his Guide Use custom USB device with Android emulator by using custom built kernel on Ubuntu 18.04
Three basic steps needed to be done.
[Update 04.05.2021]
Spoiler: Kernel Compilation
A much more easier and reliable way on how to build, mod and update your AVDs Kernel with its modules,
can be found in my [GUIDE] by using the official AOSP Build ENV.
Build the AVD Kernel with the right check at the right place
Convince Linux to actually let go of the USB-Serial Device
Grant Permissions in Android to acknowledge the new plugged in Device
The Development Environment:
Apple Macbook Pro 2011 Dualboot
USB-Serial Device Prolific PL2303 Serial Port
Linux Mint 20 Ulyana
Android Studio 4.1.1 (Software Manager)
KVM -> Cosmic (18.10) or later
Android emulator version 30.2.6.0 (build_id 6962233)
Google APIs Intel x86 Atom_64 System Image Android 10 API 29 (revision: 11)
miscellaneous
1. Build the AVD Kernel with the right check at the right place
### From the shell with the AVD running we can get some Kernel Infos:
uname -r && uname -v
4.14.175-g6f3fc9538452
#1 SMP PREEMPT Wed Apr 8 17:38:09 UTC 2020
### Install the following tools to work with and to build the kernel:
sudo apt-get install -y build-essential libssl-dev kernel-package libncurses5-dev bzip2 lib32z1 bison flex
sudo apt-get install -y libelf-dev libelf-devel or elfutils-libelf-dev
sudo apt-get install -y qt5-default qttools5-dev-tools qttools5-dev
sudo apt-get install -y geany git
### Create a working directory and download the kernel source and its prebuilt gcc:
I choose the latest android-10.0.0_r47 branch and its prebuilt gcc 4.9
Code:
cd ~/ && mkdir avdkernelcompile && cd avdkernelcompile
git clone \
-b android-10.0.0_r47 \
--single-branch https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/x86/x86_64-linux-android-4.9
I also choose the mainline android-goldfish-4.14-dev branch from the goldfish kernel source
Code:
git clone -b android-goldfish-4.14-dev --single-branch https://android.googlesource.com/kernel/goldfish
### Pull the config.gz from the AVD to generate and merge the kernel defconfigs file:
These steps lower the risk of getting build errors. And before you mod the kernel, it could
make sense to start with a build kernel that actually boots your AVD first, and then apply changes to it.
Code:
adb pull /proc/config.gz
gunzip -k config.gz
cd goldfish
cp ../config .config
make savedefconfig
mv defconfig arch/x86/configs/avd_pulled_defconfig
rm .config
./scripts/kconfig/merge_config.sh -m \
./arch/x86/configs/avd_pulled_defconfig \
./arch/x86/configs/x86_64_ranchu_defconfig
make savedefconfig
mv defconfig arch/x86/configs/merged_avd_pulled_defconfig
rm .config
### prepare the kernel with the gcc to be build:
we are now in the goldfish directory
exports must be done every time you open a new terminal
export CROSS_COMPILE=x86_64-linux-android-
export ARCH=x86_64
export PATH=$PATH:$(pwd)/../x86_64-linux-android-4.9/bin
make the just created defconfig file
make merged_avd_pulled_defconfig
If you come back here later, this is the right place to mod your kernel.
I like the GUI Interface because you have a better overview and a search function.
make xconfig
In order to get the USB-Serial recognized by the kernel, make sure the UHCI HCD is checked.
You can find it under: Device Drivers -> USB support -> UHCI HCD (most Intel and VIA) support

### build the actually kernel, with the all CPU cores you have, and see afterwards how long it took:
time make -j$(nproc)
The new kernel is placed in:
~/avdkernelcompile/goldfish/arch/x86/boot/bzImage
We leave it there for now. If you are planing to make changes when all is working so far, just jump
to make xconfig . The build time now is much smaller now. If you have to start over,
you can run make mrproper
### Start the AVD with the new kernel from via terminal
To be able to start the emulator and adb from everywhere, add those path in your ~/.bashrc
echo export PATH=~/Android/Sdk/platform-tools:$PATH >> ~/.bashrc
echo export PATH=~/Android/Sdk/emulator:$PATH >> ~/.bashrc
source ~/.bashrc
run the new kernel with:
Code:
emulator \
-netdelay none -netspeed full -avd Pixel_4_XL_API_29 \
-writable-system -no-snapshot-load \
-show-kernel \
-verbose \
-ranchu \
-kernel ~/avdkernelcompile/goldfish/arch/x86/boot/bzImage
If the kernel works proper, you can run the AVD with this even after a Wipe Data from the AVD Manager
Later on, you can get rid of the show-kernel, verbose and ranchu option. If the kernel boots and you
can work with the AVD for your satisfaction, it is time for the mod and the next step.
2. Convince Linux to actually let go of the USB-Serial Device
According to the Emulator Release Notes, one would just need the vendorID and productID from the desired USB Device to pass it through. These are easily obtained by:
lsusb
Bus 002 Device 009: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
To start the AVD with it, and you leave out the verbose stuff, the command changes to:
Code:
emulator \
-netdelay none -netspeed full -avd Pixel_4_XL_API_29 \
-writable-system \
-no-snapshot-load \
-kernel ~/avdkernelcompile/goldfish/arch/x86/boot/bzImage \
-qemu -usb \
-device usb-host,vendorid=0x067b,productid=0x2303
If you keep watching the terminal, you can see the error message:
libusb: error [get_usbfs_fd] libusb couldn't open USB device /dev/bus/usb/001/043, errno=13
libusb: error [get_usbfs_fd] libusb requires write access to USB device nodes
Now to convince Linux to let go of the USB-Serial Device, one must create an UDEV Rule.
You can do this even while the AVD is running an the USB-Serial Device is connected:
echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", OWNER="libvirt-qemu", GROUP="kvm"' | sudo tee /etc/udev/rules.d/99-usb-android.rules
After this echo command, watch while you unplug and plug it, you will only see the Info Message:
libusb_release_interface: -4 [NO_DEVICE]
And if you also watching the AVD with:
adb root
adb shell
dmesg | grep usb
You will see that the kernel is already recognizing it.
[ 619.670306] usb 1-1: new full-speed USB device number 6 using uhci_hcd
[ 620.071451] usb 1-1: New USB device found, idVendor=067b, idProduct=2303
[ 620.073050] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 620.074698] usb 1-1: Product: USB-Serial Controller
[ 620.075872] usb 1-1: Manufacturer: Prolific Technology Inc.
Btw: If you also want to use this USB-Serial Device without access issues in other tools, for example CoolTerm,
just copy the line from the udev rule and change the SUBSYSTEM to tty.
SUBSYSTEM=="tty", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", OWNER="libvirt-qemu", GROUP="kvm"
Side Note: Under Mac OS you will get a similar libusb: error, but unlike Linux, there is no UDEV System, so you
cannot change this situation at all. Also not by unloading a kext. I tried, even with EL Capitan where you actually
still could unload kexts very easily. So this just "prooves" that the Google Developers, never tried to pass an USB
through - even if they hinted it: (This should also have been workng on Linux and macOS already) And it is even
worst, there is actually a very convenient feature built in QEMU, with the -serial keyword, you can attach such devices
in no time. But for some reason, EXACTLY this feature is taken out from the Google Developers - what a bummer.
3. Grant Permissions in Android to acknowledge the new plugged in Device
With the kernel recognizing the USB-Serial Device and Linux let us acces it, the AVD just doesn't know what
to do with it. Or rather, it doesn't have permissions to proceed. To grant these permissions, one must simply
place a file, with this permissions, called android.hardware.usb.host.xml in /system/etc/permissions or
in /vendor/etc/permissions.
For both places we need not only root but also write access to it. Google Play AVD Images can be rooted, with my
rootAVD script, but these partitions can't remounted as writeable, no matter what. At least, not with my skills.
AVD Images with Google APIs on the other hand are capable of beeing rooted and writeable out of the box.
Actually, just the overlay paritions can be writeable. To achive this, one must start the AVD with the -writable-system
option. What we already doing all the time.
When the AVD is up, go with the ADB commands one by one:
adb root
adb shell avbctl disable-verification
adb disable-verity
adb reboot
adb root
adb remount
adb shell
Every command must show a positive result, if you stuck in a bootloop or so afterwards,
one of the two disable commands didn't work. Start over with a Wipe Data.
Once the remount command shows remount succeeded you are good to go.
In the adb shell:
echo '<permissions><feature name="android.hardware.usb.host"/></permissions>' > /system/etc/permissions/android.hardware.usb.host.xml
chmod 644 /system/etc/permissions/android.hardware.usb.host.xml
reboot
After the Reboot, plug in your USB-Serial Device, and If you have Serial USB Terminal installed.
it will finally pop up a message.
If you have USB Device Info installed, It will even show more informations.
If I disable USB Debugging, the 0000 Device will disappear.
That's it for now. The USB Passthrough for USB-Serial Devices can work.
I am currently working on a way to get a mass storage mounted in the AVD.
But I can't figure out the right fstab.ranchu entry for the AVD to auto mount my USB Storage.
I could get the kernel to recognize it:
[ 28.090063] usb 1-1: new full-speed USB device number 2 using uhci_hcd
[ 28.491686] usb 1-1: not running at top speed; connect to a high speed hub

[ 28.526804] usb-storage 1-1:1.0: USB Mass Storage device detected
[ 28.528787] scsi host0: usb-storage 1-1:1.0
[ 29.962957] usb 1-1: reset full-speed USB device number 2 using uhci_hcd
But it keeps getting repeated with the last line
It also does show up as block device in:
brw------- 1 root root 8, 0 2021-01-03 23:49 sda
But without sda1, just sda. And the USB Stick was formated via SDCARDFS in a real phone.
Update 06.01.2021:
Modding the Kernel with USB Mass Storage and SCSI support
In order to get an USB Stick announced by the kernel as block device node, one must
activate some additional Supports in the Kernel Config.
Device Drivers
SCSI device support
SCSI device support
SCSI disk support
USB support
USB Mass Storage support
USB Attached SCSI
With these additional features, the kernel is providing the pluged USB Stick under
/dev/block/sd which is needed to get the fstab.ranchu able to pick it up.
Once the kernel is complete, one must tell Qemu where it is supposed to plug in the USB Stick.
This is done with the -device and USB type options:
Code:
-device usb-ehci,id=ehci \
-device usb-host,bus=ehci.0,vendorid=0x8564,productid=0x1000
The EHCI (USB 2.0) driver support is already build in the stock kernel, so if you device can be
"downsqeezed" you can tell it Qemu with these words. Use the device usb.ehci, identify it for me as ehci, and attach my VendorID and ProductID to your usb-host bus ehci.0
(ehci in qemu provides 8 USB ports) With this way, you can also attach multiply USB Devices to the same AVD.
Code:
-device usb-ehci,id=ehci \
-device usb-host,bus=ehci.0,vendorid=0x8564,productid=0x1000 \
-device usb-host,bus=ehci.0,vendorid=0x1f75,productid=0x0917
If you have added USB 3.0 support in your kernel already, you can even use the XHCI driver.
Code:
emulator \
-netdelay none -netspeed full -avd Pixel_4_XL_API_29 \
-writable-system -no-snapshot-load \
-kernel ~/avdkernelcompile/goldfish/arch/x86/boot/bzImage \
-qemu -usb \
-device usb-ehci,id=ehci \
-device usb-host,bus=ehci.0,vendorid=0x8564,productid=0x1000 \
-device qemu-xhci,id=xhci \
-device usb-host,bus=xhci.0,vendorid=0x1f75,productid=0x0917
And with the fstab.ranchu correctly tuned, both USB Stick will pop up systemwide for every app to use.
Spoiler: Root and fstab.ranchu
Modding the fstab.ranchu
Without Magisk on the AVD installed, you can very easly edit the
/vendor/etc/fstab.ranchu just in the adb remounted overlay partitions.
Add this line to it:
/devices/*/block/sd* auto auto defaults voldmanaged=usb:auto
With Magisk on the AVD installed, it gets messy. Due to the fact, that Magisk is mounting a mirror of the orignal read-only partitions, some changes can't be done like before. The only way I could figure out was
to add the fstab.ranchu in my ramdisk.img and let Magisk overlay it during boot time.
Root Directory Overlay System
For this you can use my script rootAVD.sh
Code:
# Set PATCHFSTAB=true if you want the RAMDISK merge your modded fstab.ranchu before Magisk Mirror gets mounted
PATCHFSTAB=false
#PATCHFSTAB=true
# cp the read-only fstab.ranchu from vendor partition and add usb:auto for SD devices
# kernel musst have Mass-Storage + SCSI Support enabled to create /dev/block/sd* nodes
...
How to root the AVD and patch fstab.ranchu:
The script runs in Linux, Darwin MacOS and Windows. It needs the path to the ramdisk.img of the system-image as a parameter.
The AVD needs to be running and accessible via adb shell.
Then just run it and restart, NOT adb reboot, your AVD. It works with
Android 7, Android 10 and Android 11. But not with Android 8 and Android 9.
It also copys every .apk within the Apps Folder to the AVD.
./rootAVD.sh ~/Android/Sdk/system-images/android-30/google_apis_playstore/x86_64/ramdisk.img
To get the fstab.ranchu patched, set PATCHFSTAB=true, make some adjustments, and let the rootAVD script run.
Miscellaneous:
Special Cherrys for Googe Play Store AVD with Stock Kernel:
The EHCI USB Driver is already implemented in the Stock Kernel, even in the Google Play Version AVD.
By adding the android.hardware.usb.host.xml file to its rightful place, a well
written App, like X-plore File Manager, could use its own USB-Driver to access the USB Storage.
But how to get it there? Once Magisk is installed via the rootAVD script. Which are basicly the
original scripts from Magisk, just a bit tuned. You can install my Magisk Module: usbhostpermissons
Don't forget to start the AVD with usb-ehci command. The USB Stick won't pop up systemwide,
but you can still use them within X-plore and copy & paste files with it.
Replace the emulator with a script to pass arguments and run it from the GUI:
Code:
mv ~/Android/Sdk/emulator/emulator ~/Android/Sdk/emulator/emulator-original
cat <<EOF > ~/Android/Sdk/emulator/emulator
#!/bin/bash
~/Android/Sdk/emulator/emulator-original \[email protected] \
-writable-system -no-snapshot-load \
-kernel ~/avdkernelcompile/goldfish/arch/x86/boot/bzImage \
-qemu -usb \
-device usb-ehci,id=ehci \
-device usb-host,bus=ehci.0,vendorid=0x8564,productid=0x1000 \
-device qemu-xhci,id=xhci \
-device usb-host,bus=xhci.0,vendorid=0x1f75,productid=0x0917 \
-device usb-host,bus=usb-bus.0,vendorid=0x067b,productid=0x2303
EOF
chmod +x ~/Android/Sdk/emulator/emulator
If you have your original emulator file renamed, don't forget to change it when you are
calling it manual from the command line.
[Update 15.12.2021]
Spoiler: For Windows Only.
Since Emulator Version 31.1.4, Google re-implemented the USB pass through feature along with
some tools:
prebuilt Windows drivers for USB passthrough
Downloadable directly from the AOSP by clicking the [tgz]
and emulator parameters:
-list-usb
-usb-passthrough
The Windows drivers must be installed from an Adminstrator Command Shell
Code:

Now you can use those VID : PID combination to pass it through your AVD
Code:
emulator -netdelay none -netspeed full -avd Pixel_4_API_3 -usb-passthrough vendorid=0x058f,productid=0x6387
Multible VID : PID combinations are also possible
Code:
emulator -netdelay none -netspeed full -avd Pixel_4_API_32 -usb-passthrough vendorid=0x058f,productid=0x6387 -usb-passthrough vendorid=0x067b,productid=0x2303
Unfortunately the emulator will show this Error:
Code:
qemu-system-x86_64.exe: libusb_kernel_driver_active: -12 [NOT_SUPPORTED]
But the Devices are still passed through.
They will not be shown in the AVD nor recognized as a Device in any way.
In order to accomplish this, you must:
root the AVD with Magisk (Canary for 64-Bit only AVDs)
patch the FSTAB to get USB Drives automaticly mounted as a drive
install my USB Host Permissions Magisk Module
This can be done by:
Code:
rootAVD.bat %LOCALAPPDATA%\Android\Sdk\system-images\android-32\google_apis_playstore\x86_64\ramdisk.img PATCHFSTAB GetUSBHPmodZ
The Magisk Module will be put into the local Download folder of the AVD.
AVDs with a Kernel Version lower then 5.4.65 need either a custom build kernel with the
USB features enabled or an updated prebuild Kernel directly from the AOSP.
Code:
rootAVD.bat %LOCALAPPDATA%\Android\Sdk\system-images\android-30\google_apis_playstore\x86_64\ramdisk.img InstallPrebuiltKernelModules PATCHFSTAB GetUSBHPmodZ
[Update 10.10.2022]
Spoiler: For MacOS Only.
Recently I've stumbled across this Question on stackoverflow:
How to use USB with QEMU on a Mac host?
In there is a discussion mentioned, on GitHub, that kind of resolved the issue
with USB Passthrough Feature and LibUSB.
macOS: implement kernel driver detach #911
followed by a very good explanation on what is actually going on with the real reasons behind it.
How to use the new macOS kernel detach feature for non-root user no solution as of now for libuvc users #1014
However, long story short, the USB Passthrough Feature for AVDs works now If you boot the AVD with
root privileges. Here is what I did to get it working.
Install libusb 1.0.26 via Homebrew:
brew install libusb
or check your libusb version first:
Code:
brew list --versions libusb
libusb 1.0.26
I am on MacOs Monterey now:

What doesn't work is unplugging and re-plugging. The AVD needs to boot with it. Every time the AVD boots, the Disk Not Ejected Properly Message pops up. Even if it says Service authorization failed with error with return code: -536870202, the device pops up system wide.
USB 3.0 Hard Drive:
Code:
export PID="0x5106"
export VID="0x174c"
sudo emulator \
-netdelay none \
-netspeed full \
-no-snapstorage \
-avd Pixel_4_API_33 \
-qemu -usb \
-device qemu-xhci,id=xhci \
-device usb-host,bus=xhci.0,vendorid="$VID",productid="$PID"
I guess the AVD doesn't like the filesystem on that drive.
USB WebCam (uvc):
Code:
export PID="0x636d"
export VID="0x0c45"
sudo emulator \
-netdelay none \
-netspeed full \
-no-snapstorage \

-avd Pixel_4_API_33 \
-qemu -usb \
-device qemu-xhci,id=xhci \
-device usb-host,bus=xhci.0,vendorid="$VID",productid="$PID"
Conclusion:
The AVDs/Qemu USB Passthrough Feature paired with libusb on MacOs is still a farce.
Makes me wonder how Parallels Desktop is capable since kajillian years of passing any kind
of USB device through, without any root. And they have literally patch there Tools every Kernel
version.

Sorry for the late response, I didn't get any notice...
No I did not even try it. Did you?
I did but with no luck. Emulator correctly creates USB controller and /sys/kernel/debug/usb/devices contains entries corresponding with command line options but passthrough USB device is not discovered by the kernel. Sometimes emulator produces message on stdout that devices has been attached or detached but it is not repeatable. I tried different hardware accelerations ( HAXM and WHPX ) - nothing . BTW - on linux it worked like a charm - only thing I need to do was creating proper /system/etc/permissions/android.hardware.usb.host.xml. After that non modified kernel picked up usb device.

Weird, I still don't get any notice.
So you did try it on Linux with Stock Kernel and permission xml file!? -> it worked
You also tried the same thing on Windows? -> it didn't worked
Is it the same/similar AVD version? Is the syntax on windows different? What commands did you use exactly?
Is your AVD rooted? Did you cross compare the Kernel Configs? Kernel Versions?
What USB Device exactly you are trying to pass through?
Hello fellows, Did you find the way to make it work in Windows ?, It's hard to create apps that need interaction with USB / Bluetooth devices under Windows environment !, I wonder why these guys at Google make it so hard ?

It was actually already solved, the same way like on linux. But Google
decided to take out the USB Pass Through Feature on Windows.
Android emulator USB passthrough fails: " 'usb-host' is not a valid device model name"
So the only chance would be to get back to Version 30.5.2 (build_id 7175973) (Feb 27, 2021) to try it out.

Yes, totally. But Microsoft is to blame as well, according to Erwin Jansen.
I guess you need to remotely debug your apk directly on your phone/device.

No problem, If there is any USB update in the Windows Version, I am happily updating this Guide.
Hello newbit,
USB passthrough with (ASUS USB-BT400 USB Adapter USBBT400) on Linux is working fine, Emulator is able to connect to phone with BT dongle mentioned above - followed steps in android link - https://source.android.com/devices/automotive/start/passthrough
But when trying the same in MAC OS, I could see BT dongle is getting detected in Emulator as shown below (0b05:17cb) but BT in emulator not working. So, not able to connect to phone.
1|emulator:/ # lsusb
Bus 004 Device 001: ID 1d6b:0002
Bus 004 Device 002: ID 0b05:17cb
Bus 002 Device 001: ID 1d6b:0002
My question is that, In linux I have Update udev settings to allow the user process (e.g. QEMU) to have read/write permissions:
$ echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="0b05", ATTRS{idProduct}=="17cb", MODE="0666", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/99-mynew.rules >/dev/null
$ sudo udevadm control --reload
$ sudo udevadm trigger
But in MAC OS I am not sure how to do the same ie Update udev settings to allow user process to have read/write permissions ? I am not sure if this is the problem ? Are you successful with USB passthrough on MAC OS ?
I am currently blocked and any inputs on this regard would be great. Thanks

But when trying the same in MAC OS, I could see BT dongle is getting detected in Emulator as shown below (0b05:17cb) but BT in emulator not working. So, not able to connect to phone.
1|emulator:/ # lsusb
Bus 004 Device 001: ID 1d6b:0002
Bus 004 Device 002: ID 0b05:17cb
Bus 002 Device 001: ID 1d6b:0002
My question is that, In linux I have Update udev settings to allow the user process (e.g. QEMU) to have read/write permissions:
$ echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="0b05", ATTRS{idProduct}=="17cb", MODE="0666", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/99-mynew.rules >/dev/null
$ sudo udevadm control --reload
$ sudo udevadm trigger
But in MAC OS I am not sure how to do the same ie Update udev settings to allow user process to have read/write permissions ? I am not sure if this is the problem ? Are you successful with USB passthrough on MAC OS ?
I am currently blocked and any inputs on this regard would be great. Thanks

Hi @nrajeevlochan,
as mentioned above, Mac doesn't have this UDEV feature like Linux has it. Depending on the Mac OS Version,
I had to extract and copy some dylib files from a newer Mac OS Version to my running Version. The Error
output was gone, but the USB Device wasn't passed through. So for now, I cannot provide something useful to get the USB Pass through feature running on Mac OS. The only, non-convenient work around is, to adb remote connect to your Linux AVD. But you need either 2 separate Machines or a virtual Machine running in your Mac. Which will cost you a lot of performance. Is there any error message on the terminal regarding your USB?

My apologies @nrajeevlochan,
I didn't even notice that you've replied to my question.
[ 205.405316] usb 1-1: can't set config #1, error -32
indicates, that the AVD actually detects the device, and can even read some low level information from it.
Like Product, VID, PID etc. But the host system doesn't fully let it go, so this error can't set config #1, error -32 shows up, indicating that state.
I do have some positive updates tho, you might wanna check out the
[Update 10.10.2022]
For MacOS Only.
Cheers NewBit
