OTG not working - OnePlus 5 Questions & Answers

Hello, I have an OnePlus 5 with OxygenOS 10.0.1 and I'm trying for the first time to connect a pendrive to it, throught an OTG cable.
I insert the pendrive and nothing happens. I tried several devices but it can be detected by the phone. I also tried to turn on "OTG Storage" option, but nothing changed.
Since not even the light of devices turns on and since the same pendrive with the same OTG adapter works in friends' phones (I tried Xiaomi, Oppo and Samsung), does it mean that the OTG feature of USB port is broken at the hardware level?

Won't recognize USB stick

I can connect my V20 to a Windows PC via USB cable, and transfer files back and forth. I had to pick something on a menu the first time I plugged in the phone.
However, if I plug a USB stick directly into the V20, it does not recognize it, or respond at all. My friend plugs the same USB stick into his V10 and an app pops up and shows the folders.
I'm using a micro-USB to USB-C adapter on the stick to plug into the V20. I know the adapter works, because I tested it when connecting to the PC.
I have searched settings for "USB" and it only comes up with USB tethering.
This is an AT&T stock phone, using the stock launcher. No root or anything.
Any idea how to get the USB recognized on the V20? Thanks.
it might be that the USB host function doesn't work with those adapters. have you tried plugging in a USBC to USB adapter and plugging a flash drive into that?

I've tried the same thing without success. My note 3 & 4 worked fine. I also had a Note 7 and Nexus 6P and it didn't work with those either.
has there been any advancement on this issue?
Did anyone find the answer to this? My V20 used to boot up a USB stick but just stopped working one day.

USB-C hub not working

Hello fellow OnePlus 5 owners,
One of the features I was looking forward to the most on my new phone is USB-C, since I always hated that to use any USB device on my previous phone I had to drain my battery. I purchased the Ableconn USBC-4APD USB-C hub from Amazon with pass-through power but I am having problems.
When I try to connect the hub, the phone only recognizes power and shows it's charging less than one in a dozen times, and if I then try to connect any USB device (USB flash drive, keyboard) the LED's on the peripheral just flash once and nothing else happens.
I have tried the same flash drive and keyboard with a regular OTG cable and they work fine. I had a co-worker with a Pixel phone try the hub and it passed through power every time (I did not have a flash drive along to test), it also works as a hub on my laptop (did not try passing through power on that).
My question is, has anyone else tried a USB-C hub, and did it work? Is there something wrong with the OnePlus 5 (hardware/software) in general or something wrong with mine in particular, or is there something wrong with the hub?
I'd appreciate any help in figuring this out.
Is the USB-C cable from the OP5 to the hub an USB-C OTG cable? If not, I suspect that is your issue especially as you indicated the OP5 is recognizing the input to be at least a trickle charge. To my understanding any data access and it would be restricted to read only, requires an OTG cable and the OOS OTG setting to be toggled to on (Settings->Advanced->OTG storage). If you gave TWRP recovery installed you can also check the OTG capability by mounting OTG in the Mount menu as a test access alternative to within OOS.

You misunderstand, the USB-C hub does not require a cable to interface with the phone since it has a USB-C cable attached. I didn't indicate that it at least trickle charges, I said that it rarely recognizes getting charged, as in there is no charging indicator on my phone most of the time.
The OTG setting for storage was enabled, however based on you mentioning the switch I disabled it, and it actually detects power every time I plug the hub in to it with OTG storage set to off. This gives me hope that it's a software issue and can be fixed with either patches in the future, or more likely a custom ROM. I was planning on installing TWRP once Lineage OS is available, but I may try it sooner just to give this a try.
Thank you for the reply!

LG G6 Otg doesn't work

I have a LG G6 H873 and I'm trying to use an OTG adapter to read an SD card (Kodlix Type-C Reader) and I'm not getting any prompts for a USB device being detected (and the LED doesn't light up on the adapter).
I've tried the same adapter on my wife's LG G5 and it works fine (both os are at the same revision). I've also tried the "OTG Troubleshooter" app which seems to detect that a OTG device is plugged in. Plugging a USB cable from my PC to this device works fine and I can browse the files on my phone from the PC.
Any ideas?
Same here. OTG worked fine. Then one day stopped working.
My phone recognizes all my files in file folder but stock gallery and music app showes no pics or songs.When i flashed oreo update my sd card worked fine.on boot up it would show media scanning and then show a little sd card icon in the notifications but after 2 days my phone does not scan anymore.Is this related to your problem?
I have a G6 h870ds. After loads of mucking about I have discovered that my OTG only works with full USB3 OTG adapters and USB3 memory sticks.
I cant use USB2 wired OTG adapters or USB2 memory sticks. Initial connection of the USB2 OTG adapter is recognized but no connected devices are detected. I have a USB2 memory stick with an LED on it. When it is first connected to the OTG cable it flashes in a way that leads me to think it is trying to reply to the USB bus interrogation but something (probably software) fails. The phone connects to my usb2 PC port just fine so I don't think the hardware is at fault. I've reset the phone but alas that didn't help!
No issues whatsoever if I plug in the OTG adapter first, then the drive. No matter if USB 1, 2 or 3 memory stick.

[Q] USB OTG behaviour

Hi,
So I'm developing an app to communicate over serial with a HID and testing on the g6 is proving troublesome.
The scene:
-Hid/USB Permissions granted
-Device filter correct and working as intended
-Goal is to send a string over serial.
Allthough I'm 100% sure my test code is correct, the app cannot open a serial port.
Is it normal behaviour in recent versions of android for the device to recognise an otg cable as a power source? Even with no other device connected? Are there any known issues opening serial ports on the g6? (7.0)
The cable works as intended when I plug a mouse or keyboard in but refuses to open a serial connection when my takget device is plugged in. It recognises it as a HID an can pull the serial number etc.
The android serial library should not require root or any other hackery So I'm a bit confused. I've ordered a few other otg adapters just in case.
Anyone who knows what might be going on pleas pitch in.
I've had some issues getting a serial adaptor working as well. I'm on 870DS. Originally tried the wired version of this:
https://forum.xda-developers.com/an...odemu-connect-android-to-30pin-t3234840/page1
Thank God the developer changed to Bluetooth. I tried about 6 different otg cables. Worked fine on other non usb-c phones.
I suspect it is the adapter too...sucks so bad. The annoying thing is that I was so confident in android serial that I wrote a lot of code before I bothered testing the concept lol.
Does your OTG work on memory sticks OK? I have a G6 h870ds. My OTG only works for me with USB3 OTG adapters and USB3 memory sticks. I don't have a USB3 HID device to try. I now have a large collection of different OTG adapters and memory sticks. I opened up some of the adapters to buzz them through to make sure they were made correctly. They were! It took a while for the penny to drop why some things worked and some didn't!
I cant use USB2 OTG adapters or USB2 memory sticks, keyboards or cameras. Initial connection of the USB2 OTG adapter is recognized but no connected devices are detected. I used an app called USB Device Info that can give me details of detected devices and only USB3 devices are ever detected.
I have a USB2 memory stick with an LED on it. When it is first connected to the OTG cable it flashes in a way that leads me to think it is trying to reply to USB bus interrogation but something (probably software) fails. The phone connects to my USB2 PC port just fine so I don't think the hardware is at fault. I've reset the phone and upgraded to Oreo too but alas that didn't help.
A friend of mine has a G6 H870S and all my adapters and memory stick combinations work fine on his phone so I find myself wondering if I'm just unlucky or whether the dual sim version is subtly different in some way.
I fully admit I know nothing about the inner workings of USB but as far as I can determine USB3 uses all of the USB2 connections and the additional connections only available on a USB3 port so the hardware should be OK. I'm guessing most HID devices are USB2 but if its a USB3 could you possible have a related problem but in reverse?
Every time I plug in any USB OTG adapter I get that same pop up screen that defaults to select as "power supply" even with no device connected whatever I have previously chosen.
What works for me is to plug in the OTG adapter, and only then plug in the memory stick to it. Otherwise I get the "Power supply" thing too.

Leaving just the OTG adapter connected for a few seconds then attaching the usb device does not help. USB2 devices are never detected but all my various USB3 memory sticks work reliably when using a USB3 spec adapter. I've given up worrying about it now and accepted that there is just something a bit iffy about my G6.

Yoga Book YB1-91L USB port problem

Hello everybody. Asking for help and suggestions. Maybe LENOVO representative take notice. Have secondhand yoga book. Resolved almost all problems but micro USB port. First of all, charging device died out. Find 30-watt charger with QC 3.0 and charge now working perfectly. Next tried to connect mouse, usb hub and usb dongle. Each time got DEVICE NOT RECOGNIZED message. Got error in device list.
But......tried to connect external HDD with noname HDD box and it connected. Connection may work to copy, install files or disk may disconnect randomly.
Tried system restore, tried to change drivers ( intel drivers for chipset not avaliable now) with no luck. Think problem is with low port current, but even small mouse and dongle make error and non-SSD HDD work 9 times out of 10. Have anybody experience problems with connecting devices to micro USB port?
Tried 3 different OTG cables and OTG micro USB to USB dongles. No luck.
Maybe the port is corrupted or desoldered

I did change it with the warranty I had. I had the same problem and did not want to fix by myself as the warranty was still active
