[Q] OTG Stopped Working

So I bought one of those cheap (sub $1) OTG adapters from Amazon, and up until today it worked. I was able to import photos from my digital camera and use a USB mouse. Today I can't get it to work at all. Not the mouse, not the camera, not anything else.
Regular USB (charging and PTP mode, I would have tested MTP as well, but it's not compatable with my laptop) works fine. I'm able to transfer files to and from the tablet, and it charges fine.
Is something wrong with the OTG cable or my tablet? Will I have to buy a new OTG cable to test?

If its only <$1 just get another one or two! Sounds like a cable problem if everything else is working

Christmas is coming, I see the shadows of Ebeneezer Scrooge !!

Are you using stick mount to load the OTG onto the N10? If so thats probably why. When i first installed my stickmount it worked but wouldn't see any of the files on the USB drive. Now after i've unlocked and rooted the device it won't even show the usb drive attached. I switched to Nexus media importer and it works fine, but i believe stickmount is having issues with 4.2.
However if the OTG cables did cost you less than a buck replacing them may be the solution too.

OTG support

I bought a type-c adapter for my Z1 to use OTG cable and Usb key. The key does not power on. I tried the adapter to charge the phone with a regular usb cable and it works.
Is this problem related to COS or is OTG function not supported on the Z1? Or is there a way to enable it?

I don't know if that has changed but for cm you have to use an app like StickMount to be able to mout the USB stick.

Ok thanks, I guess I have to root then.

I used only es file Explorer and it worked for me. I testet Ext hdd, mous, keyboard and controller

Same, no root required, just an usb C OTG and a file explorer. Be aware that the OTG or the device could be uncompatible...

I bought a USB-C to USB-A Converter and it works for me. Official USB type-c adapter has no support for OTG.

" type-c adapter for my Z1 to use OTG cable and Usb key"
What speed did you get to ?
Lenovo Zuk Z1

I tried Xiaomi USB typeC adapter with a SanDisk micro USB memory and it doesn't work

I have the same problem.At my oneplus 2 with adapter working normal but at Z1 not working.

No solution about that ? I got 2 adapters now (noname and Victsing) but still no otg, and usb storage options are unavailable !

Does it support in twrp recovery.. i mean does otg recognising in twrp...???

Strange, it should work out of the box on COS 12.1...just received my second Zuk1 and hooked up the Z1 to my car to read out the ECU, it worked without an hitch! Did not try a USB stick though...
I have 2 cables, one is with the micro USB for which I use a micro USB to type C USB adapter, the second USB OTG cable already has already the Type C connector and connects straight up.
I never used my "charging cable" as the idea is to plug your USB stick straight onto the OTG interface cable.

i have rooted/unlocked zuk z1.
tried every possible stuff (es file explorer,stick mount, usb troubleshooting etc), tried changing the otg cable, tried changing pendrives, nothing helps.
can anyone please help me?
xda is my only hope

Does xperia x compact support OTG ?

I change my phone to xperia x compact recently, I find the type-c USB is easy to use.
I have a otg usb drive with micro usb, which is working on samsung s7, dell tablet. I wonder if it can be used on XC.
Thanks

Not sure about your micro USB OTG drive, but I purchased a separate OTG type-C adapter which connects to my USB card reader just fine.

I tried to use a type-c to micro USB adapter, it doesn't work. Maybe I have to buy a type-c otg adapt first.

May I know what brand is your adaptor? I tried a couple of OTG type-C microSD card readers, but none of them work.. it simply don't seem to be providing power to the adaptor.

I could use a mouse using:
mouse -> usb to micro usb otg from z1 compact -> micro to usb c adapter

Even this doesn't work for me. My phone seems not being able to act as USB host and not recognising anything plugged in the type-c port. My phone is rooted, not sure if it's the cause.

I use the sony type-c dual flash drive and it works flawlessly

Still not working. I used a voltage reader and found that there is no voltage coming out of the USB port, no wonder it won't detect anything. No sure if my phone is faulty (doubt it, as the port works perfectly when it is USB client) or due to setting/rom/kernel...

Do you have a pop up screen asking you what to do when you connect anything to the USB port?
BTW, my USB OTG adapter is of a brand REMAX.

no, nothing happens as if the phone does not know something is connected. but works ok when connected to another host (pc or power source)
i'm using rooted 7.1.1 stock rom

Thanks! Finally i got it to work. Sorry that I had been trying type-c usb reader instead of a true type-c otg adaptor + reader... so, it fact it would work with a type-c otg adaptor.

Support USB OTG

Does the G6 support USB otg? The reason I'm asking I bought a borescope camera and can't see to get it to work. Camera only cost $10 and if I can get this working I can sell my $1300 Snap-On camera that is the same thing

Same thing? Really?

I think he's basically referring to storage and photo quality together

Yes it is support usb otg

Meaning I can use it to look through spark if hole or injector nozzle to see cylinder walls. Resolution should be almost identical except I have a HD+ screen on my phone that may help it look a little better.

Did you pick up an otg adapter dongle? The one I have is the "Anker USB-C to USB 3.1 Adapter".

No but I'll definitely pick one up.

I ordered that exact one works perfect. It's weird I have a different adapter that didn't work I guess it's for charging only.

At the top of the screen from the notification area, it showed USB icon and you can click on it to see files.

I didn't found solution for my problem, and i think there is no need to open new topic, but if you know - help me!
From purchase my H870I had a problem with USB OTG.
When memory card micro SD is inserted and mounted, everything is working properly.
When I connect USB OTG USB adapter with USB flash drive, or USB OTG memory card reader, then in notification area is "Android System - Reading USB Drive" all time.
In System settings - storage
is the information about internal memory and and memory card capacity and usage, and "USB Drive - checking"
In that state a cannot access any file on memory card. For example I can see photos and albums, but after opening one of them there is icon, that file is corrupted.
I need to reboot phone to memory card work properly again.
To see files on USB OTG device i need to unmount memory card in settings, and then plug USB OTG. After unplugging USB OTG I must mount memory card again.
Did you have a similar problem? I must say, that back to factory state, and oreo update (also last ThinQ update) didn't resolve my problem. Do you have any solution? Can you give your ideas to resolve this problem?

I'd try a second usb flash drive. If you get the same hanging issue, I'd expect it's something bad with your usb otg adapter. Sometimes an adapter might work okay with one phone, but be kind of on the hairy edge and not work with a second phone.
I use the anker usb c to usb otg adapter a lot with my g6, since I first got it over a year ago. I do transfers to multiple flash drives.
Good luck!

I tried a different USB card reader, and it's working perfectly. Thanks for help!

USB OTG a few things tested...

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!.

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.
