I installed it in my dash and removing it is a pita it was working perfectly fine but for some reason it wasnt showings charge or turning off or on with the car it just stays on i tried restart nothing happens i tried unplugging usb from powergen and plugging back in no result
Also if i go to usb rom under fixed installation i am able to check box and uncheck also did nothing
I am using nexus 7, timurs usb rom, otg cable, original charging cable and powergen usb charger
Please help thanks
Anyone???
I'm also using Timur's kernel with USB ROM for my car installation. I know that it can be very picky on the order the USB plugs are added (data and power). It may seem simple but remove the the OTG cable from the tablet and remove both the data and power legs from the OTG as well. The follow the order listed by Timur on his website:
To activate charging, you must first connect your external power supply to your OTG Y-adapter - then plug the OTG adapter into your Nexus 7 - and then connect any slave devices.

Hopefully that should get you back up and working. I completely understand how frustrating it is to have everything plugged in and see that tablet isn't charging, especially when its difficult to get to the Nexus itself.
does anyone have a easy charging solution these car chargers dont work
and a good otg y cable
You could try using a power inverter which will give you a standard US plug from the cigarette lighter. From here, you could plug in a regular outlet adapter. I found this to work pretty well with my own set up and managed to get one pretty cheap at Walmart. As for a good OTG y cable, your best bet is probably to go on Amazon and find one with a lot of good reviews. They can vary in quality and some of the cheap ones I've gotten from China have flaked out after a short time and little use.

Not seeing usb power
I had the same issue. I was using a 90 degree adapter into an OTG cable and my n7 wouldn't go into fixed install mode. Turns out my adapter cable was stopping the n7 from recognizing power. I removed the 90 degree adapter and plugged straight to otg and it worked as advertised. The issue was found during my bench testing on a 12v powersupply. I still have to find a 90 degree otg cable that will work.
So... try a different cable or if you have an adapter between the otg y cable, that may be the issue.
I've tried a couple of devices that claim to connect V20 to tv by wired usb c to HDMI connector. They work for a while then the picture is lost or the phone itself freezes up. About the longest play I've gotten successfully is an hour but usually something goes wrong within 15 minutes.*
The phone has been out over 6 months now so I thought someone may have found a really dependable HDMI connector? I don't mind the lack of power in because I can always change batteries but phone should be able to play through HDMI long enough to watch one movie. That's all I really need hut I don't want to have to screw around with it 10 times to watch one movie.
Thanks so much for your help!
I've been wanting to make use of this feature, but haven't extensively yet. I have though gotten to make fair use of a micro-USB to HDMI adapter. A few trouble spots come to mind here.
Sounds like you're powering the adapter/phone from an external power source? How good is that power source? My micro-USB to HDMI was distinctly less reliable when plugged in since I was merely powering it from a normal USB port. Try running it entirely from the phone's battery. If this works better then it could be you really need a higher power source when using the adapter.
How good is your HDMI cable? Depending on how strongly the phone/adapter drives the HDMI signal, a lower quality cable could break the camel's back.
I've been running into a different bit of trouble with USB-C to HDMI adapters. I've found several of these, but whenever they've got a USB-C pass-through, the pass-through is strictly for power and does not carry the USB signals. The MyDP specification allows for USB3 to be passed through if 1 or 2 pairs are used for the HDMI signal, but allows for USB2 to be passed through no matter how many pairs are used for the HDMI signal. There are adapters which also include USB-A port(s), yet none which include an external USB-C with the USB signals. Grr!
I use C to HDMI not micro usb. V20 doesn't use micro usb. It uses slimport. I have one adapter which allows simultaneous charging and one strictly slimport C to HDMI. Both behave the same way. I have a high quality 2.5 foot HDMI wire.
Power source was Samsung tv usb powered output 1 amp. Point is I have the same issue with pure slimport and no charging.
The one that allows simultaneous charging does in fact charge and work but always craps out but so does the slimport C to HDMI.
Hmm, entertaining what you find when you do research. I suspect the V20 is using the "MyDP" specification, which is the official specification name behind "Slimport". Seems there are at least two other video out methods for USB-C.
I haven't done enough with the video-out feature of my V20 to have much experience yet. With a V10 whenever an adapter was plugged in without external power there were no problems, but when an adapter with external power was plugged in video wasn't reliable.
I'm interested in reading if you find out anything.

Sorry I haven't tried, but its seems to connect smoother the a wifi dongle.
does anyone know if there's a compatible dongle for the V20 with not only hdmi but also power input and usb host?
Happening to me too - Any suggestions
Your situation's description fits my problem exactly. I have a USB C to HDMI that was vouched as working by several V20 owners. I plug it into my Dell monitor to play games on a bigger screen. It works well for a while, then disconnects and popup on my screen says something like, "LG Bridge has stopped working do you want to exit?". Once this happens, it's almost impossible to get the V20 to share the screen again. It's not a hub, just a USB C (male) to HDMI (female).
I've no idea if this will be of interest to any of you, especially those people who have yet to buy a 5t and are trying weigh up the pros and cons, but USB OTG is something I use all the time, so o it was one of the first things I tested when I got mine. So far I'm really pleased as everything I wanted to work does so. My last device, a Xiaomi Redmi Note 2, had very poor USB OTG implementation so this is great from my point of view. Maybe I'm behind the times and I had the last phone on the planet with that problem - if so, please delete this mods
First off, before you can use USB OTG, you need to head into settings, then advanced and check the OTG setting. It turns off after ten minutes so I created a link on my homepage using Nova launcher's activity widget menu.
*EDIT* As ny-hardcore has kindly pointed out below, you can also have an OTG quick toggle in notification area. This didn't work for me at first (or I was hitting the wrong thing), but now it does .
Tested and working:
USB card readers of various types, including micro USB readers, with the help of a USB C to Micro USB adapter (5 for £4 on eBay!). The only one that didn't work is a proprietary Samsung multi card reader that also has a full sized USB output and HDMI out too. This isn't very surprising of course, but they're to be avoided if you see one on eBay and assume it's a generic adapter.
80 GB iPod hard drive in a cheap enclosure bought via Amazon.
1 TB 2.5" Western Digital HDD - that's right, no USB hub required, just plug it straight in. The only other portable device I've owned could power it was a Samsung tablet.
2 mega pixel boroscope (using USB Camera app in Play Store) . So useful for finding slow water leaks under the floor or peering down a spark plug hole into a cylinder!!
Micro USB DVB TV dongle, via adapter.
Keyboards and mice via an OTG adapter, including a combination media keyboard with built in trackball mouse (this usually doesn't work on my phones for some reason). The UK keyboard layout is supported via settings so you can have a £ key - woohoo!
Other phones! I plugged my old phone in and discovered I could mount it in MTP mode and then browse its contents from the built in file explorer. For what it's worth, the Oneplus even charges the device that's connected to it.
When you need to eject the device there's a button that appears in the notification area. Sometimes this gets obscured, so swipe down a second time and the 'eject' will appear.
I haven't tried any game controllers yet, but so far the support has been so comprehensive I don't see why there would be a problem.
In the attached photo, the only thing that doesn't work is the black coloured multi purpose card reader on the far right.
In quick toggles you can add an otg switch.
You don't have to go in settings that way to enable otg.

Thanks, for some reason that just didn't work for me unless I went into settings/advanced as well. I can't recall which firmware I was on at the time and I haven't tried since The quick toggles are so far away for my little hands too (please Oneplus add a Xiaomi one handed mode - in fact, make it EXACTLY like Xiaomi devices).
LOL, typical, now it does work for me! I was probably pressing flight mode by mistake or something.
Just FYI, I've tried the following USB DACs with an OTG cable on my 5T and they appear to work:
- Fiio E17
- Meridian Explorer (v1)
- Audioquest Dragonfly (v1)
I just discovered my old Saitek X35/X36 throttle/joystick combo works too! That's a first for one of my Android devices too. Now I need something fun to test it with

Has anyone gotten USB sound cards to work *for recording*.
Like I have a Terratec Aureon USB MkII and would like to livestream my DJ sets to Facebook via the FB app, by hooking up the line-out on my decks to the line-in on a soundcard hooked up to my phone and have the streamed video use the soundcard instead of the internal mic which sounds rubbish.
Edit: Tried it, and yes it works, but you have to hook up to the mic port, not the line in, and this doesn't seem like a great idea. Any idea how to change it?
Edit2: Scratch that, phone rebooted itself during a longer test

That would be so cool if you can get it working. Wonder if it's the phone or the Terratec? I have NO experience in that area. Good luck! How much power does it draw? Would a powered USB hub in the mix help?
Hadn't thoughtof the power draw issue.
What I really need is a super cheap low power USB line-in of some sort. Though after further testing, FB live streaming is crap, with low quality audio and video in all the configurations I tried (Android app, Win10+Firefox, Win10 app) so I'm probably going to abandon this plan and try a different platform like Youtube or something.
Just cant get otg to work in my device, I am on OOS 4.7.5, rooted with SuperSu, tried a type c to micro USB adapter, also a type c to USB 3.0 adapter, I have enabled the otg option in advanced settings before plugging in the devices, I don't know whether its the phone or the adapter I use, what kind of adapter did you buy, is it a type c 3.1 to micro USB 2.0/ USB 3.0, could you provide me with a name of the adapter.

I have the following USB OTG adapters.
2 X micro USB to full sized USB (the long type with a two inch cable).
1 X mini micro USB adapter that is tiny.
1 X micro USB adapter (bigger than above)
1 X USB C OTG adapter with micro SD card reader built in.
All of the above work. In the case of the micro USB OTG adapters, I'm using a USB C to Micro USB adapter (they're tiny, about 2 CM long).
In short, every USB OTG adapter I've put in it works. All are unbranded, generic adapters that I've bought from Amazon or eBay. I've never had to do anything more than enable OTG in settings.
Could it be something to do with the ROM you're using?
In the attached photo, the ones with a yellow Mark are micro USB OTG adapters. The one with a red mark is a USB C multi card reader (built in USB OTG). The one with a blue mark is a USB C to Micro USB adapter.

Sadly what you're doing is way beyond anything I've tried. I'm happy when I can get card readers and stuff to work
I vaguely recall reading about specifications for the older micro USB ports on phones and what type of power output they supported - not all were equal. For example, there were a bunch of Samsung phones and tablets that could power hard drives without needing a powered USB hub inline. Similarly, some could power an MHL connection to a TV without the adapter being plugged into a charger like most phones that supported MHL had to. I've forgotten the name for these specs, but presumably USB C is exactly the same and it'll be online somewhere. No idea what your Terratec draws or if that could be the problem - if our phones can spin a 1 TB hard drive then perhaps it's not an issue, I was just clutching at straws.
Good luck!

4.7.4 Stock. Stock recovery too (not rooted either).
USB OTG worked on stock 4.7.2 as well.
Working fine for me, stock, custom roms etc. Use a cableconnection usb/otg cable 6" in length. Just enable OTG in the swipe down, plus USB stick in...no problems.
I gave up on using the phone for this because the audio quality via the FB app is terrible anyway, so I nicked my GF's Windows laptop and started using OBS for streaming instead.
Power aside, it's awesome that an external sound card will work (kinda) for recording though!.

On which ROM version are you on, is OOS 4.7.5 or another version of OOS or some other ROMs.

Thanks for the reply, I am beginning to think that it kind of an issue with OOS 4.7.5, I have to flash the old version and try my luck on it.
Hi guys,
I intend to use an old s7 edge in car with a USB DAC (Mini USB DAC signstek audio -- PCM2704). I plug into the car.
Since this DAC requires a power source from the phone, it works and audio comes out, but now I have no way to charge the phone.
I am so confused with all these issues with cables and hubs. I saw Nexus 7 had a special timur usb host kernel rom or something...
What's the bottom line... how can I power the phone and the DAC at the same time and have the DAC plugged to the phone?
Are there roms I can use or special modifications whatever, what cable/hub? Please let me know.
I'm ready to root this phone and install a custom rom, but want to use it for this purpose
Instead just buy a cheap fast wireless charger.

It's either USB-OTG or charging, you can't have both as hardware limitation (and i don't think any phone has that capability), unless you wireless charge
then how do those guys with the nexus 7 charge and have a dac at the same time with a Y cable?
i have nexus 7 with Y cable, but it works on some rons with enabled charging. thats why usb cable had many pins
