"fastboot devices" shows no devices - General Questions and Answers

Hi,
For some reason, "fastboot devices" shows no devices when I connect my LG G Stylo MS631 in the download mode (a.k.a. the firmware update mode) to the PC. Not sure why that is and what could be done about it.
Any ideas? Thanks

More info: when the phone in the dowload mode connected to the PC, in the log I see the following:
Feb 06 10.06:22 tst kernel: [969014.956096] usb 1-2: new high-speed USB device number 37 using ehci_hcd

"fastboot devices" still shows no devices though. Any ideas? Thanks

Help with usb serial device

Hi, when i connect an Huawei 3g usb dongle i see this in dmesg:

Thanks for any help!

[Q] Can someone help with ADB please?

ADB flatly refuses to recognise my Xoom MZ601.
I run ADB on my Debian Linux computer and it recognises my LG Optimus 2x (P990) which appears in the list provided by 'adb devices' the same command with my Xoom produces 'List of devices attached' with nothing underneath. The USB Debug setting on the Xoom is ticked and the computer recognises the device. The computer's log shows:
Jun 24 12:10:37 dataman1 kernel: [3605717.696244] usb 1-7.2: new high-speed USB device number 67 using ehci_hcd

The udev 51-android.rules shows:

# Bootloader

I have run out of ideas. I am hoping to root the Xoom soon so any suggestions would be greatly appreciated.

It is nice of you to try and help but a Windows executable is not going to run on a Linux machine. There are drivers already on the Linux machine because, as I said in my post, I can use ADB to connect to my LG Optimus 2x.
Wasn't there some udev rule that needs adding?
Sent from my HTC One using xda app-developers app
Maybe use WiFi adb? That's another solution that will probably work. I'm sure you can find an app easily enough. Or does stock android has it by default? Don't really remember...

I'll give that a try and report back.
spychodelics: I have added udev rules as shown in my first post.
Thanks to you both for trying to help.
Update: I have now solved the problem. With some Linux kernels, mine included, if the ehci_hcd module (needed for USB 2.0) is loaded it prevents the Xoom from being recognised so a modprobe -r ehci_hcd will unload that module and, Voila!, my Xoom is now recognised by ADB. I imagine a fix for that bug will be issued sometime.

Nope. In my case I think it's driver related because other card work but I can't install the linux driver for the MT7601U due software dependencies / 404 error

understanding if fastboot is enabled on mi a3 with broken screen

Hi *,
I hava a xiaomi mi a3 with broken screen, i already rooted and enable debugging previous of the broken.
Now i would use scrcpy but adb listing my device as unhautorized.
I see in other post that i need to copy the key on /android/data/..., but i unable because adb shell does not work, so i read that entering in fastboot mode i able to copy the files without key.
So i powered off the phone and restart with volume up+power and i see this on my syslog

so seems that product, vendor and device id is different.
Could someone confirm that the first id, of product vendor and device is fastboot device?
There is a method to solve this impasse?
Thanks a lot to all
so the vendor product and device is different
Fastboot gets enabled by default when an Android device boots up, unless manufacturer ( e.g. Samsung ) decided not to support Fastboot. But Xiamomi devices support Fastboot, AFAIK.
FYI: Fastboot isn't a device you can find in /dev/block, it's a software that allows to operate on Android device's bootloader.

Hi and thanks for the answers, but I think that Linux discover fastboot device with different product vendor and device id respect normal boot. I would know why fastboot command does not discover my device, I suspect, because my screen on device is broken, that device not start in fastboot mode and I ask to group what kind of product device and vendor I'd you seen for your xiaomi mi a3 device under syslog or lsusb in fastboot mode.
Yes
Code:
sudo ./fastboot devices
returns
Code:
<SERIAL_ID> fastboot
but that's NOT AN ANDROID DEVICE, IT'S THE DEVICE'S BOOTLOADER connected to, and nothing else.
If the output is shown as above listed, then Fastboot-mode is enabled/activated and working.
