USB OTG Not Working - Nexus 6P Q&A, Help & Troubleshooting

I am currently having an issue with my USB OTG Flash Drive. This drive, and other used to work fine when plugged in. Now it doesnt show up at all in the phone even in recovery. The flash drive works fine on my laptop, and the phone itself transfers fine to a laptop.
They used to work, but I cannot remember if it stopped after a certain ROM/Kernel update. I do know that it was NOT working on the prior version of Pure Nexus + Elemental X, nor is it working on the current versions. I state that because to upgrade between those 2 versions a clean flash was required, so that did not fix the issue.
Any ideas?

I'm looking at this issue too. Hope we can get some answers. I'm looking at re-flashing the factory image this weekend to see if that works.

This happened to my 6p while on Screw'd 7.1.2 ROM, I wasn't even done backing up all of my files when OTG simply stopped working. Tried all sorts of things even powering the flash drive using a USB y cable, still nothing. Must be a controller issue because the phone connects to a PC no problem but ignores OTG devices completely.

How's the drive formatted?

Vega 1.09 ROM, installed USB mode switcher with odd results

Hi all,
I've been loving my Vega since getting it a few weeks ago, but have noticed a bit of an issue with the latest firmware. When I installed the Modaco USB Mode Switcher tool, gave it SU permissions and switched to host mode to allow usage of a thumb drive, it rebooted perfectly. I copied over the files from the vega that I needed, and removed the USB drive. Switched mode and rebooted and now when I go into wireless settings, under Wifi it shows Error, and MAC address shows Unavailable. This happened twice now, I reflashed the device thinking I had arsed about with something I shouldn't have changed then installed things one by one testing for a day or so after each install and no sooner had I installed the USB Mode Switch, it happened again.
Is it just me? Have I got a duffer, only it worked ok in 1.08.
Cheers
Pete
I have had some trouble with the usb switcher with my rom add-on, thats why i removed it from that thread. I seems to change the boot.img some how. Last time i tried it it changed my green android icon back to the old Booting..... Looks like it needs to be updated for v1.09 firmware.

Thanks OG. Glad it isn't just me. Cheers for your hard work by the way.
So is it not possible to ennable usb host mode on the 1.09 firmware then? This is such a shame because i needed to use my usb pen drive with my vega...... will it be possible aanytime soon?
Thanks
Notch another one with troubles using the USB switcher ...
Yup, had the same thing last week. I installed a clean 1.09 and added OG's clean addon. As there was no usb mode switcher included I installed it from the modaco rom. After a reboot my wifi stopped working, too. I flashed the device and switched to the latest modaco rom (apparently that puts you back to 1.08, though), but dont have much of a choice because I really need the usb switcher.. Hope OG is able to find a fix for this issue..

[Q] OTG quit working after 4.2.2 Update

My son and I both have Nexus 7's, WIFI version. Both are running 4.2.2. The only difference between the two is mine is rooted his isn't, yet.
We both have Media Importer loaded but here is the issue. Ever since he upgraded to 4.2.2 his Nexus will not see any devices connected to the OTG cable. Mine works fine, he has tried my cable and I have tried his. It's definitely not the cables. His laptop recognizes the Nexus and it charges fine so we ruled out the USB port.
Any ideas what might be the issue on his end?
Thanks!
I am on 4.2.2, rooted and OTG works fine. I seem to recall root was needed to use OTG, wasn't it? Was OTG working on your son's N7 before the update without root?

You don't need root if you use Media Importer. Yes it worked fine prior to the update.

Powerdown Video
Hey there,
I was finally able to install this rom after a long Sunday of learning and failing and finally succeeding late last night. My question is in regards to the powerdown video that is supposed to play in the case of power loss. Is it supposed to play every time disconnect my nexus 7 from power? I haven't installed it in my car yet but I've been playing with it and it doesn't do anything when I disconnect it from the power source. Anything I might be missing? I have the following options turned on: Fixed install mode, fast charge in host mode, and firm sleep. Any help is greatly appreciated!
Need some help
Running Autodroid 1.2
Issue #1 Everything seemed to be running great rebooted on Sunday and now it no longer recognizes my usb charging cable or Otg cable. So power down can not take place as well as charging . What do you recommend? Should I re-flash the kangaroo kernel that is on the 1st page?
Issue # 2 I am using a usb hub with a charging port for my setup. I want to use a behringer UCA 202 dac . How should I set this up?
Any help on either would be great.
Newbie Autodroid summary and Nexus 7 car solutions in general
I apologize if this is the wrong place to post, but I'm trying to do a Nexus 7 in dash head unit replacement and I have some questions.
First, a little about myself. I'm an Android (and XDA) newbie, first post, but I have some programming experience (C and some assembly). I am rapidly learning about Kernels, ROMs, etc. I try to learn as much on my own as I can so I won't be a pain here. I know wiring, and am an electrical engineer.
My problem is this; I need a solution to allow the Nexus 7 to OTG charge, or maybe it's possible to use the side dock connector for charging? If I OTG charge, I read that Autodroid may not support that, but Oxydo does? I could really use a source of information (youtube video etc.) so I could learn how to make this work.
And, for that matter, how to program my Nexus. I've seen how to root it, and I think I can do that, but then should I flash it with Oxydo kernel and then Autodroid ROM?
Any help would be greatly appreciate. I'm trying to get this up for myself and for my 17 year old son's truck. Also, thanks for all your sharing of code and help!
Autodroid supports Otg charging as is.
What I would do is go to the play store and download MuliRom manager.
This will make it easy to set up MultiRom.
Multirom lets you install and uninstall multiple roms without messing with your stock rom.
Hope this helps
USB issues
Ok I have been running autodroid for a few weeks. So far it is good. I am having a few issues though with it.
Has anyone been having issues with charging since adding this ROM. Although it is charging it doesn't indicate that, so otg doesn't work. It can't see any usb attached items and such.
My setup includes a Behringer usb dac uca202. Although I plug the dac in the hub (sometimes without the hub) and reboot the devices from off I still get not response; the dac light does not light up, sound still comes out of the tablet speakers. Can Anyone using this setup help me figure this out or at least put me on the correct path
I want to add a backup cam to my system, but there appears to some real issues with this setup. Any help or advise would be great. I want to be able to have it come on as soon as i put the car into reverse

Thanks! That's an interesting idea. I may try that. Are there any disadvantages to this approach besides the extra storage space (which seems like it wouldn't be that big of a deal?)
I just rooted the device, so it's fresh and ready.
On the other hand, I found someone with Timur's ROM, so I have two options now. Autodroid seems a little more up to date, but I'm not sure. Maybe it's just a preference?
Thanks for your help. I know a lot about a lot of things, but in this area, I feel a little like I"m walking around blind! I'm just trying to learn as much as I can.
I don't see any disadvantages and the storage space is minimal.
With MultiRom manager you can also remove the rom as easily as you installed it.
It has a multi boot feature on startup so you can run your stock rom or any other roms that you have installed.
Autodroid is a rom and and Timurs is a kernel. With the Autodroid rom you will have a lot of features which are geared toward an in car installation.
If you decide to use Autodroid don't install it like they show in the op.
There is an easier way to do it using MultiRom.
Advice please
Can I plug in a FIIO D3 into a powered Anker USB hub. I have tried 2 behringer UCA 202 and both connect but no sound from either. I have read the USB ROM tutorial and I know that I must turn the devices off them mount the dac and turn the device back on, but still I get no sound. Help me

That sounds really cool.
I know Autodroid is a rom, but I thought Timurs is a kernel and a rom?
Autodroid can be had at the play store if you sign up to be a tester. I wonder if this is a different version, or I guess somehow it's changed into an app?
If I use multirom, how should I install autodroid?
Thanks so much for your help!

The first thing is to get MultiRom Manager installed and working and then we will go from there.
When you have installed the app and opened it you will see a box that says install/update.
If the first two boxes match what is in the status box above this you are ok, if not check these boxes.
If you see a warning in the status box about the kexex hardboot patch, check the third box and in the drop down menu pick which version of Android you have,
If you aren't sure of which version you have, on your tablet go to setting about tablet and it will show the version.
Tap install and follow the directions.
When this is susessful we will go to the next step
Is there any way to make navigation bar bigger ? I need it to be two times bigger.
What should the ROM look like when installed correctly? This is my first time doing a custom ROM and it appears to be installing correctly but the OS is not any different it seems. It just has Apollo and SuperSu. No additional features anywhere it seems. (Nexus 7 2012 Wifi)
It says....
Kernel Version

I rooted and installed CWM. Downloaded the ROM for the first post, wiped dalvik, wiped cache, cleared everything, and then installed the ROM from zip. It doesn't appear to be working unless I am just missing a step. I tried using my new Behringer UCA222 with my OTG Y cable. UCA222 has power, tablet charges, sound plays from tablet speakers....
Any help to get this working out be nice. I don't know what I am doing wrong.
I have noticed a problem with power event manager!
I have disabled waking the screen on power because i can wake it up anytime using my remote control.
The problem is that if my screen is off and there is a power loss then power event manager sets airplane mode but the screen is switched on and stays on.
Anyone elese is having the same problem?
FI Problem
Hello,
i have a Strange Problem with my autodroid System.
In the Power Settings, it is not possible to set up the FI Option.
Everytime i change these setting, it goes back to off.
Because of this Problem, i checked the Autodroid installation an did a new, fresh install.
Changed the OTG Cable and the Power Adapter.
Nothing changed this
I tried again an older 4.2.2 Rom, here workes everithing perfecly with the same OTG and Power Adapter.
Because of the 4.4 Android, i would most likly use Autodroid.
But without a solution for this Problem, i could not use it in my Car.
And i read here, that other Users didnt have the Same Problem.
What did i do Wrong here?
Best Regards
X2 on a bigger navigation panel¡
I am having a problem with everything on the usb hub being restarted everytime I turn off and turn back on. So it has to rescan media, and i have to accept dialogs to use the FM tuner because it doesent remember it used to be there. Is it because i am using stickmount? I have it in locked mode, and I thought thats what it was there for...?
Edit: fixed the issue, I didn't realize the Rom had built in functions for mounting the external drives.
Rear View Cam
Hi,
I posted this in the ROM-thread before, but got informed to post it here in the Q&A thread instead, so it's kind of a double post.
Tried to search the thread but didn't really find the answer, but does this ROM still rely on Carcam as the app to show the video feed from the Easycap, or did someone actually write a new app?
Love the work on this ROM, as I loved the Kangarom before it. This is going in the car, if I can just get the shaky Carcam to actually work after a deep sleep as well...

Than i downloaded autodroid 1.2 and when i went into recovery mode and started the install, and it gave me an error mess saying E:Error in /sdcard/0/autodroid.zip (i shortened the file name) (status 7) Installation aborted. when i restarted the nexus 7 it give me error on bluthooh and clock. any help would be great. I have done a lot of research. Maybe i missed something. thanks in advance.
Trouble Installing Autodroid 1.2 on Nexus 7
So I've been attempting to install Autodroid 1.2 on my Nexus 7 Grouper, but I can't seem to get the bugger going. The tablet originally had Lollipop (5.0) installed.
So here is what I did:
1) Installed the stock 4.4.4 ROM (Build Number KTU84P)
2) Installed Bootloader 4.23
3) Installed TWRP 2.7.1.1
4) Installed SuperSU (rooted the tablet).
5) Performed a normal wipe.
6) Installed Autdroid 1.2 for Grouper
After doing the above, and going to the "about tablet" setting, it displays the following:
Kernel version: 3.1.10-kangaroo
Build Number: KTU84P
So it looks as though the kernel installed fine, but the ROM itself doesn't look the part.
A few more things to note, OTG seems to be kind of funky. I can insert a USB drive and mount it using Stickmount, but the drive doesn't show up under Settings->Storage.
Oddly enough, charging with OTG works.
Any help would be very much appreciated.
Hi guys, can some one explain me how to wake up my nexus after disconnecting from charger?? What should happened is power event manager should wake up n7 when charger plug in but nothing happening so when i press button on side to turn it on it will on but system doesnt recognize charging, but when i plug same charger on working screen then everything is fine im using normal cable not otg, is it a problem that its not otg?

Lost OTG after Installing Kali Nethunter

Hello,
I installed the kali kernel and net hunter as per http://forum.xda-developers.com/axon-7/development/kernel-kali-nethunter-zte-axon-7-t3520280 and everything booted fine. I could net get my external wifi adapter to be recognized so after much troubleshooting I noticed that my phone no longer recognizes the otg cables: i cannot mount a flash drive any more or use my sir with sir touch. I refreshed my back up and all work. Anyone else having this issue?
Hadn't thought to test it as I was still fighting with my wifi adapter but it would appear that OTG doesn't work for me either using the latest build
I saw your post just after I made this one. I to struggled with the wifi adapter thinking it was the adapter till I tried out the OTG cable. Hopefully it is a quick kernel fix.
yeah I noticed this too, it wasn't happening before I uploaded the kernel so not sure what happened there.
It's most likely related to the DWC3 driver updates from mainline being unstable.
I'd reflash stock system & boot followed by SuperSU for now until I resolve it.
I'm working with a new kernel base at the moment which I plan on rebasing NetHunter onto but I haven't finished solving the audio issues.
Update: Looks like it's due to the HID gadget patch, though not sure how it's interfering. Maybe the USB descriptors are incorrect. :S

Question Issues after flashing the stock ROM

Hey, I have a few issues after flashing the stock ROM of the Nothing phone 1. First of all, I can't wirelessly charge the phone (but reverse wireless charging works.) I know my pad is QI-Certified and does support 15 watts. I also tried it with a different one, that worked in the past. Second, I can't use the OfflineOtaUpgrade to install Nothing OS 1.5. As mentioned, I had to flash the stock firmware/ROM since the phone somehow got stuck in fastboot mode. I'm having these issues since I reinstalled it, before that everything worked fine. Would be nice if someone could help me.
