is there a way to use a regular usb otg cable on nexus 4, or not?
im thinking anout buying one, and i plan to root and remain on stock, but a deal breaker is not having expandable memory. is there a way to mount an otg cable, like stickmount on the nexus 5, or something?
There is a way to use usb otg on the nexus 4. You need to root and flash a specific kernel and you need a usb-y-cable.

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, I'm trying to access a USB storage on my nexus 7, got a few different apps but nothing. Does the nexus have to be strictly rooted in order for it to work? Or can i do it on stock? Im stock btw.
Thanks.
There's a Nexus Media Importer app that will let you read from USB storage through your OTG. But if you want read and write capability, you'll need to root your device and use a root level app like Stickmount.
Hi
Somehow when i connect a 16GB USB stick to my note 3 via an OTG cable it shows
1. USB connector connected
2. USB mass storage connected
then immediately
3. USB mass storage removed safely
so i cannot see anything from my USB device connected via an OTG cable
for instance my 16GB sandisk USB stick is not mounted anymore
it used to work with 4.3.xxx but not with the latest update of 4.4.xxx
also Air Droid can't write anymore so it's useless
my USB stick is ntfs formatted, would that be an issue?
i have Paragon exFAT, NTFS & HFS+ installed but it says it has no root access, i have the stock rom and not rooted. it used to work with 4.3 but now with 4.4 it does not work any more
thank you

NTFS will not work on android. Format your usb to exFat or fat32, or read this

actually i cannot format my flash, it's full and i don't want to loose the data
thanks anyway
Erhm copy files to PC,format stick and copy back The files?
Respect!
thanks, that would work if i'd had a computer with me. i'm away from home and was hoping i can mount my usb stick. is there a solution that does not require root access?

Not that i know of.
You can try to install the USB Host Diagnostics and check what is happening, on this app the root is optional.
i have no doubt that the USB works but the ntfs file system cannot be mounted directly by the OS so it unmounts it immediately after connection.
so my question still remains, is there a way to mount an ntfs file system without having root access?
thanks
Can anyone confirm that OTG works with TWRP? As in I can install from OTG flash drives like the Kingston MicroDuo 3C or SanDisk OTG Dual USB 3.0 all while still remaining encrypted?
No Idea about encrypted since I have unencrypted since I got my device. I can say that TWRP works with OTG. I have not backed up to the device yet. I always flash and back up to OTG. I have also succesfully restored from it as well. I use a USB Type C OTG cable and 128gb USB flash drive.

Ok thanks! I guess I'll just have to try it when I get the drives. Hopefully it works.

Odd. I can't backup or restore anything for my OTG. My OTG USB has a mini usb, so I use the USB Type-C to USB standard-A adapter from Google.
It always shows on TWRP that my OTG has like 175 MB or something extremely small. never shows the files I have. I have reason to believe that the OTG being detected isn't my OTG at all. This is because it showed an OTG with 175 mb even when I never had it plugged in.
Thoughts?

Make sure you format FAT32 or will not be recognized.

Most likely your drive has a small FAT32 partition that you did not realize and the rest is not FAT32.
Encrypted or not at this point is moot.
With no microSD, unless I tell you, you won't know.
You can backup, restore, copy to/from using the computer utility.
OTG works encrypted or not.
I am wondering if it is possible to charge while having a HDD attached to the tablet? is there a special OTG cable required? Do i need to be rooted? when i hook up the regular OTG cable i can either transfer or charge, I cant do both
