3.2 does not support USB thumb/flash drive

I just updated my US Xoom WiFi to 3.2. The SD card is working fine and it is shown under mnt\external1. However, I still cannot access my USB thumb/flash drive even I have a Motorola OTG adapter. Looks like 3.2 does not support USB thumb/flash drive. Any suggestions? Or I have to root it and install a custom kernel to make it work? Thanks.

I'm wondering the same thing. Will have to flash another kernel...
Who uses thumbdrives and USB discs these days anyway?

Uhm, everyone?

USB thumb drives and external drives are supported fine on 3.2, download USB Mass Storage Watcher OTG from Market
follow the quick guide and all works great.

I understand, but I mean on stock 3.2 without root, which the OTG app needs.
Or did you got it working without root?

my xoom is rooted, i am not sure of any USB OTG apps that work without root. I will do some research.

After updating to 3.2 with root, I tried USB Mass Storage Watcher OTG and first it complained about an old version of busybox , then after it updated busybox, it would just FC when I plugged in a flash drive.

I wonder what is the reason that 3.2 still does not support USB mass storage. I wish this will be addressed soon.

If it is any consolation to you, my 3g Telstra xoom on 3.1 with sd card support and usb enabled still doesn't work unless i have an OTG cable and USB Mass Storage Watcher OTG. Usb works fine for mice etc without usb mass storage watcher.

[Q] Native USB OTG Storage Support

Hi,
there are many ROMs out there for our beloved Nexus 10, but it seems that only few support external storage via USB OTG. I couldn't figure out how to enable it manually. Is there any kind of mod or kernel that does the trick? I tried some apps on the play store, but I don't like the idea of an app sitting between the android system and storage hardware.
Thanks in advance!
Cheers,

I think all custom kernels have USB OTG support in them, and maybe I am ignorant since I dont care about OTG support but I thought all "major" ROMs worked with them. Hmm.

Maybe you're right, but in that case USB OTG seems not to necessarily include USB OTG storage. I noticed, that while ParanoidAndroid did not recognize my USB storage device, it was still able to detect things like mouse and keyboard correctly.

Example:
[ROM+KERNEL] [AOSP] AOSP+ 4.2.1 - JOP40D - Cust.Settngs+OTG+OC+More - 20 Dec 2012
http://forum.xda-developers.com/showthread.php?t=1998585
USB OTG Information:
1. Auto-mount to /storage/usbdisk
2. Files accessible by all applications, processes and users
3. Currently works with FAT & NTFS partitions
4. Full read-write access for FAT USB disks, read-only access for NTFS USB disks
5. This does not conform to the Android 4.2 multi-user capabilities. All users have full access to the OTG storage
6. If you are using another custom kernel, make sure it does not overwrite the ramdisk changes or you make lose OTG support
I am sure there are other ROMS. Do a "OTG Support" search in the "Nexus 10 Android Development" forum and find what suits you.

Cm 10.1 and AOKP both support native OTG for USB drives. :thumbup:

ROM? try root + StickMount + *browser for root
ops! i didn't read the last part of you post :/

thanks for your replies,
it seems like the only up-to-date ROMs that aim on native USB OTG storage are indeed cm10.1 and aokp.
however, apascual89's paranoidandroid might soon support it too.
i think that is worth having an eye on it.

[Q] USB host controller issue

No device connected to the micro USB host through OTG cable is detected. Neither mouse nor keyboard or (micro) SD Card. The kernel claims to support USB host controllers. Checked with three different OTG cables, all sold claiming to work with Nexus 7.
Everything was also checked on stock ROM and kernel (JDQ39) unrooted and rooted.
Same cables work like charm with my i9305 Galaxy S 4 LTE just as Stickmount and Nexus 7 Media Importer (mouse, keyboard, storage).
Nothing works however with my Nexus 7. I feel very frustrated and cannot resolve this issue no matter what I try.
Any ideas?
Thanks
Nexus 7 grouper, rooted, Stickmount, Busybox installed
OS: JDQ39 based Smooth rom 5.1
Kernel: M-Kernel 3.1.10

Try a different kernel... Bugs do happen so OTG might be brought ken on that kernel.

PS: I know bricked worked, I thought Franco's worked too. Dunno bout M-Kernel, I actually avoided that kernel because it didn't look like USB-OTG support was in it when I searched the thread.

Thanx answering
I'll try Franko. As I remember, M-kernel has OTG support. But
Shouldn't even stock kernel support keyboard and mouse over OTG?
And why does the Nexus Media Importer app not work either? That
doesn't even take root...

Depends on how you're implementing it. I know with apps like StickMount and OTG Helper, they won't automatically start media scanner on the new device unless you have the paid version.
The rom in my Sig actually has USB-OTG support for the Nexus 7 built in (would still need a kernel that supports it of course), so it automatically mounts a thumbdrive, and it shows up under Settings -> Storage , and shows as USB Storage and you can unmount it from there, acts just like an SD card would on other phones. Only downside is no exFat support (nor NTFS I think). Stickmount can do it but you have to provide the exfat binaries in /sdcard.

Stickmont free detects connected USB storage immediately and mounts it. The USB drive and the files on the device connected by
OTG can be seen by any file explorer in a normal case. Also, when connecting mouse and/or keyboard (even wireless)
via OTG/OTG&USB hub a USB icon and a USB device connected message should pop up in the notification
bar. Nexus Media Importer app should also see the connected device if formatted FAT32.
At least, that's how it works on my Galaxy S3 using the same hardware ( 3 different OTG cables,
mouse, keyboard, USB sticks, memory cards, etc.)
I have flashed four different kernels (M, Motley, Franko, Stock). There is a significant difference in
performance but unfortunately not in USB host device detection behaviour.
I do appreciate all your helping effort. Thx

How to have working USB OTG on Android 4.4.2 KitKat

Hello.
I have Samsung Galaxy Note 3, SM-N9005 Snapdragon version.
I bought USB OTG cable from dx.com, with microUSB 3.0 for S5/Note 3.
When I connect mouse or keyboard, it works.
But when I connect USB flash drive, or external HDD it mounts, but after 3-5 seconds it un-mount.
Is there any way, fix or some xposed module to have it working?
I have rooted my phone and I am running on custom ROM (CRASH ROM v16), based on stock XXUGNG1 PDA, Ultimate Kernel v55.
Thank you for your help.

It won't mount NTFS drives. Try a usb drive on fat32. It will work.

I faced the same problem when I bought my Otg cable. Here's what I did maybe it helps.
I copied all my flash memory and external hard drives content on my laptop then I formatted them in exFat and it was immediately recognized by the stock rom android 4.4.2 N90005.

I have Samsung galaxy grand 2 and i need use USB OTG android version 4.4.2 how can i use it tried more times and not work
