USB Host Diagnostics reports that it can detect my USB device.
My rooted Nexus 7 has Stickmount and I would like to read and write to the exfat filesystem.
Does the stock kernel support exfat, I am wondering if this is the problem that I can't see any files on the USB Key.
If so, has anyone compiled the exfat.ko or have some workaround ?
I am fairly sure that the USB-OTG cable is fine, it's been recommended several times

Using my rooted stock kernel with StickMount, I was unable to see any files on my USB drive formatted as exFAT.
I tested the same drive formatted as NTFS and FAT32 and they worked just fine. Searching around other forums, it looks like the stock kernel doesn't support exFAT.
It's possible that a custom kernel could support it, but I haven't found any specific kernels with exFAT support.

Hi,
I am using Paranoid 3.0 + latest M-kernel and I am encountering an issue where I cannot write to USB drives.
Reading from the files works fine but I cannot create anything (files or directories).
I have tried with two different FAT32 formatted USB drives.
Do you know what could be the case here?
Thanks!
I couldn't find anything on TeamWin's main site or in various google searches. I know for sure that TWRP supports Fat32 via the USB-OTG cable, but I was wondering what other formats it would support, such as exFat for example (to use the same thumbdrive to store media files over 4GB for example).
My Kernel/Rom supports USB-OTG as well as say NTFS, but I'm curious if exFat would be possible (far as I know the M$ patent on it seems to suggest maybe not).
PS: any recommendations on a good auto-mounting script for the OTG, basically something that can detect and auto mount to /usb-otg or another folder, perhaps even a widget I could just tap to mount/unmount.
PS#2 : StickMount seems to be working rather well (exFat support too as long as I have the fuse binaries on /sdcard). I'm actually browsing a 1TB Toshiba USB drive off the OTG cable right now which is formated as exFat. I'm probably just going to keep a 8GB Fat32 thumbdrive for my TWRP backups (which also happens to be my memtestx86 drive which is mostly empty anyways).
Guess I needed to look at their actual thread. Seems they do support exFat.

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
Hi all,
can you guys tell me how to detect ntfs hdd with usb otg on official kitkat rom?bcoz i stored all my data on ntfs hdd which i cant reformat to exfat
before i upgraded to kitkat, i flash the adam kernel then install a software called paragon. then it works
as you know adam kernel did not support kitkat. so, is there any other way?without adam kernel, the paragon software did not detect ntfs
ah yes, i really would like to stick with the official rom for the mean time...so there's no chance i'd flash a third party rom
thanks in advance for the help.....:laugh:
Google Nexus 10
Android version 5.0.1
Build Number LRX22C
CWM 6.0.4.7
Rooted
I have just installed the Android 5.0.1 update AND purchased a 64Gb Sandisk USB/MicroUSB memory stick.
My Nexus 10 can mount the USB stick without any problem and I can see and use all the files on it but because I had to format the USB stick as NTFS all these files are now read only so I cannot delete any files from it nor can I move files from my Nexus 10 to the USB stick.
Does anyone know if there is a way to coax my Nexus 10 to be able to read AND write to my NTFS USB stick/drive?
Thanks
Hi,
AFAIK the kernel has to support NTFS writing. There are some on development section, you may want to search for it.
Good luck,

I use the playstore app USB OTG Helper but you will also need to install SELinux Mode Switcher and set that to permissive mode. Despite the USB OTG Helper app displaying an error (-9) when an OTG SD reader is attached it provides the full RW access your looking for. It also provides multiple formats support beyond NTFS. I personally use Linux ext4 on all my SD cards which is also supported. It has an experimental exrFAT support but I've never used it.
There is also Stickmount but I prefer the way USB OTG Helper added the external storage to the device. It seemed to integrate with my music player better, that may be personally choice though.

Thanks for that. I will give both a try and see which is best for me.
Thanks again
Well I have tried both and whilst both seem to mount my USB drive and both seem to acknowledge it is mounted, when I try to delete a file which is on the USB drive using ES File Explorer I get the error message of "unsupported operation"!?
If either of the pro versions have something that the free version does not, that will get USB read/write working I will happily buy pro version but no point if not working
