As I understand it, the device would recognize a flash drive
but the system software doesn't explicitly know that the USB A
host port can hold removable storage, so it needs to be manually
unmounted. I figured worst case I could use ADB or terminal shell
commands to sync and umount?
thanks

Hi all! I have an HTC desire that I love. My dad got a mesmerize the other day and I do think it is a great phone. I want to root it for him and remove all of the bloatware. I don't really want to do custom recovery/kernels. It was purchased today, so it has 2.2 out of the box on it. Could someone point me to a tutorial for rooting it? I am confused with super one click of what things to do (like unmount the memory card or what usb debugging mode to put it into). I assume that freezing any app in titanium backup would be fine? Such as allshare/ my mini diary, etc.
Thanks!
Go into your settings, and click USB settings, and there should be three options, Samsung Keis, Mass Storage, or ask.
If you set it to Mass Storage, it will prompt you to mount the SD card when you plug it into a computer. Clicking mount mounts the SD card and pops open a window on your PC for copying files and such. As far as I can tell, when you mount the SD card, you can't do USB debugging. (FYI, USB debugging is enabled in Settings>Applications>Development)
If you choose Samsung Keis, plugging the phone goes straight into USB debugging mode, assuming you have USB debugging enabled. You might be able to get USB debugging mode from mass storage mode if you do not elect to mount the drive, I'm not sure.
Anyway you probably know this, but in non-nerd speak, USB debugging mode is for programming your phone, synchronizing it, and other related tasks. You're going to want to put it into debugging mode any time you want to make changes to the phone's software framework, like flashing kernels, rooting, and other general havok. So now regarding that Superoneclick program you mentioned? Just plug your phone into your computer in USB debugging mode (meaning DON'T mount the SD card) and then you can just click ROOT in Superoneclick from your computer, and it will give you root access on your phone. Its quite easy. As far as I can tell, you don't have to "unmount" your SD card so much as you simply just don't mount it. When you plug it in, you're prompted to mount the card. Don't, or set the USB settings to Samsung Keis beforehand.
There's not much to the instructions, its literally just
1) plug in using USB debugging mode (don't mound SD card)
2) Open Superoneclick and click "Root"

Oh, and make sure you have the drivers for your phone. That's important. If you need drivers, they can be found in the first post of this thread:

Thanks so much. You answered my question perfectly.

Is there a certain driver I need to use for USB Mass Storage access? When I use a Sense ROM, Windows recognizes the phone as an MTP device, but when I use an AOSP ROM, the phone shows up as a "My HTC" device in the Device Manager, but never shows the phone's sdcard as a drive. Is there a certain driver I need to use? I'm running Win7 x64.
EDIT: Turns out my computer was using a really old HTC driver (from 2008) to identify the phone. I let it update and find another driver for it, and it used the generic USB Mass Storage device driver and added the Linux File-CD Gadget USB Device to the Disk Drives tree. I'm not sure how this will affect how Windows recognizes the phone when I use a Sense ROM, but for now this works.
tl;dr If the phone shows up as My HTC in Device Manager and doesn't show up as a USB Mass Storage Device/Linux File-CD Gadget USB Device when you enable USB Mass Storage Mode on the phone, try letting Windows find a new driver for it automatically.
Be warned that this will probably break ADB access, and you will need to keep the HTC Driver on hand to switch to when you do need ADB.
Re: Can't use USB Storage in AOSP ROMs
I have the same question. Mine just shows up as "removable storage", and I can't access anything. I instead transfer files wirelessly over WiFi using ES File Explorer, but I'd still like to know how to access the phone through USB.

Are you mounting as usb storage when prompted by phone? Disable HTC sync on the computer?

I am indeed mounting when prompted, and I'm not sure how I'd disable HTC Sync short of deleting or otherwise uninstalling it.

I have xoom mz 601 everest. i have rooted it, with latest rom 153.
there is no problem in my usb otg, I am using it to view files from my normal usb drive.
but there is this one thing. I can't make my external hard disk to work.
After i connect it to the usb otg, it looks fine and i can see that the power is not an issue, because it runs just like plugging it in a laptop.
but then, the xoom, notifies me saying, "SD card is damage. Try reformatting it",
the external hard disk works well in my laptop, i know there is no real damage in it.
How can I make it work in my xoom?

This has happened to me as well - as a precaution, copy your needed files from your sdcard to your pc for safe keeping. Take the sdcard out of the xoom, place it in a card reader on your pc, bring up the command prompt for that drive.
You can run Check Disk from the command prompt. At a command prompt, you can test the integrity of the "E" drive (whatever your sdcard drive is)" we will use "E" in this example. Typing the following command:
Code:
chkdsk E
To find and repair errors that are found in the "E drive" (your sdcard drive), use the following command:
Code:
chkdsk /f E
That should fix it.
thanks... What i did is just use an app that will mount it, and it mounted as is there is no damage it was said...
Hello,
I pluged the device to my laptop (win 7 pro 64bit) and have chosen the driver mode, installed the drivers, then i want to access the mass storage mode to transfer the files using file commander, but the only modes are charge, MTP, PTP, driver disk....i cant see the internal and external storage as a disk in any mode. Please how to fix this?
I might be wrong, but I do not think Lollipop supports USB mass storage anymore . You should still be able to transfer files in and out via Windows Explorer using MTP mode. And I actually like that because I no longer have to worry about ejecting the device before unplugging.
Usb Mass Storage (UMS) is no more officially supported since Jelly Bean 4.2.2. Nevertheless we can find some app/mod enabling it (on playstore) but I don't know if or works with 5.0 + and root is needed.
As the title says: Is there a way to connect an MTP device to a Poco X3 via USB OTG? As in the X3 should be the host, the opposite of what happens when you connect in file transfer mode to PC
Mass storage devices (eg. a flash drive, external SSD) work just fine, but MTP devices (eg. another Android phone in file transfer mode, a Nintendo Switch in copy to computer mode) simply don't elicit any response from the X3
My question is, is there a way to get the phone to recognize these, perhaps by means of an app?
(I can root the phone if necessary, but I would rather keep this stock if possible mainly because it's a real pain to set everything up after unlocking the bootloader)
