Need OTG + Power Rom - Nexus 7 Q&A, Help & Troubleshooting

Hello,
i am desperatley in need of a ROM for the 2012 Nexus that supports USB UTG and Charging.
I would be thankfull for every Info with a working Download-Link to a ROM.
Thanks!

I need it too. And I'd like to have undervolting feature. But looks like you should find ROM by yourself and then flash kernel with OTG+power

FWIW I flashed my 2012 N7 with LN14.1 build 20180625-UNOFFICIAL, OTG and charging work fine, however MTP connectivity to Win PC only works when the N7 is booted into TWRP recovery.
See https://forum.xda-developers.com/nexus-7/development/rom-lineageos-14-1-nexus-7-2012-t3530261 for download and installation info.

I am also looking for a way to use a music player from usb/powered usb hub/fat32 60G card in dash car mount.

[Q] USB connector question

Hope someone here can help me.
I have rooted and unlocked my Nexus 7, and now I am able to use an USB stick to put my movies/music/books on. Which works great most of the time. But, I do come across a tiny problem. Its impossible to charge my Nexus while using the USB stick, or the other way around.
Do they exist, USB connectors for in my Nexus 7, with 2 USB-plugs, so I can at the same time charge and use my USB stick for movies?
It's possible with an otg y cable and a kernel that allows this mode. HERE a Thread about this function.
Thanks for the answer, but as I am not an expert on Rom/Kernel. I have paranoidandroid 3+ installed with stock kernel. What kernel would be recommended for this to work?
Try M-Kernel a46 if you have an y cable.

USB 3.0 with MTP on AOSP ROMs

Okay so I am really stuck here... hopefully someone can help me
Connecting my S5 with Samsung Stock ROM to my Laptop (Windows 8.1) via USB 3.0 cable gave me three options:
USB-Connection (PC):
connect as
MTP
PTP
MTP (USB 3.0)
Now I have tried AOKP ROM and also CM11 ROM for my S5, but as problemless as USB 3.0 support worked while on STOCK ROM..... as confused I am now....
Connecting my S5 running AOKP/AOSP ROM with USB 3.0 cable to my Laptop now only gives me these two options:
MTP
PTP
When copying files with AOKP/AOSP ROM running its obviously NOT USB 3.0 speed. I am quite sure my Laptop has the required drivers installed, as USB 3.0 support worked just fine with the Samsung Stock ROM.
I thought this must be a well known problem/issue. But so far, I looked hours on Google and no answer found.
I also posted in the Cyanogemod Forum - Galaxy S5 Support Section --> no reply
I am really really stuck. I feel like there must be an easy solution, but I just don't get it..
So really would appreciate any help you can offer!
Thanks!

(Q) Nexus 4 OTG

Good day everyone, I would like to ask why my phone does not support OTG. I need your suggestions.
First my nexus 4 runs on Paranoid Android Rom v5.1 with quanta kernel v18. I also made my own otg y cable by connecting the red and black wires. I tried to use otg but my phone does not connect to my flash drive. When I connect it, the phone charges and the flash drive blinks its led light so it means that my wiring is Ok. What could be the problem?
You need to use Stickmount.

Usb audio issue - dac not working

Hello,
First of all Nice to meet You !!
Lastly I rooted my p9 lite and activated USB OTG. It is possible to plug in pendrive mouse etc and it works fine :good: .
The problem is that I cannot make my portable DAC xDuoo XD05 working with P9 Lite. I tired everything.
When I plug it in there is no reaction I tired different usb option /cables - no result. Apps like USB AUDIO PLAYER give notification that android did not find any devices and probably my device does not support USB host mode. I'm asking You for help as I am totally disoriented what can be done as I'm not expert for sure.. to make a use of DAC / USB AUDIO option.
HUAWEI VNS-L21
EMUI 4.1.1
Android 6.0
This DAC xDuoo XD05 is connected by usb OTG right? The phone may not have the driver to support the DAC, it happens with a lot of device if the phone does not have native usb OTG support.

Hello,
Yes exactly it is connected by usb otg. Maybe it is possible to get and install driver or any other way to make it working? I saw on the forum similiar cases for other phones so I just wonedring if it is possible to make it working on p 9 lite
I don't think it's possible to manually install drivers. Some kernel and custom ROMs are build with every driver available in the kernel source. You may try Veno Kernel but they said that it is not very stable on EMUI.

Ok I will try it. But firstly I need to find some instruction how to do it thx
Take a backup of boot partition on TWRP and flash the zip that you can find in the ROMs&Kernel section of Veno Kernel. If something does not work good you can restore the backup
I have error while flashing unsupported device
I think it's because you are on EMUI 4, it is still not fully supported.
I'm still looking for solution so if anyone has any ideas please share with me
Hello,
Finally I found solution.
I connected Xduoo via usb hub to my p9 lite. Usb audio player pro found my device and it works perfectly now. Please share this tip to anyone having similar issue.
Nice!
