I'm guessing here, but do you mean a usb device? not usb drivers? Drivers you would install on your computer, a usb device u would plug into the other end of an OTG cable, right?
If you're talking about a usb device, like a usb stick, before connecting the usb stick with the otg cable, go to the development options and page down about 2/3 of the way and you can select what 'type' of usb connection to make... one is charging only, etc etc.
the one to select is MTP (media transfer protocol), then the usb stick should work.
Yes it's USB device, when I am trying to connect it via otg cable in my mobile it's doesn't open in my mia2

If the file system on the usb is ntfs then it won't work
In any case, if it still doesn't work, you can use this app

So it wasn't working on the pie beta but I didn't bother writing it here because I thought it was a beta so meh. Now since it's stable now, I am still unable to connect my Flash Drive to my phone. When I connect my usb to it, it does recognize the USB but then that's it. Like when I connect my usb, it doesn't show the usb in the "Files" or even in my 3rd Party files explorer. When I drag down the notification panel, it actually shows that a device has been connected and when I tap on that I'm redirected to a menu where there are 2 options. so is anyone else facing the same issue on Mi a2 or is it just me? Or am I doing something wrong?

I have the same issue. Tried with Mi A3 (Android 10) and it works normally. Plug into Mi A2 (Android 10) and it shows that device connected. Android System notification says -> Charging connected device via USB, tapping it shows USB Preferences. USB Preferences show that Usb Controlled By -> Connected Device and doesn't allow to change the option.

both of you should use stock pie stable miui and it will work.
for extra certainty try mixplorer and give it root with magisk and select the custom.otg driver option
in many cases the otg adapter you are trying to use might be crap ..
in many cases the charging port wasn't working and repair soldered on an unofficial part now it can only charge and otg or usb cable data to pc can't work
options:
1. connect usb to usb port on your router and use samba plugin from mixplorer to access it over the network ...
2. connect usb to your mia3 and send the file with midrop to.your mia2

Android Auto Wireless - Play music from USB?

Just wondering whether anyone using Android Auto Wireless has had any luck in getting music to play through the phone's USB port?
Specific issue here is wanting music to be played through the phone's USB port, in order to make use of a USB DAC attached to the phone.
So still using the AA interface on the headunit to control the media app (e.g. UAPP), but for media playback to go via USB.
Thanks :good:

phone > developer mode > usb audio routing (i believe debugging needs to be off)
or
headunit > usb
you may need a new cable due to not having compatible connections for audio output.
(my oneplus will only open aa with its original red power cable)
currently trying to get it to connect to wireless but seems to be having a metal breakdown

Question USB-C headphones (Oppo MH135-3) doesn't work

Hi guys!
I bought headphones USB-C Oppo MH135-3 and tried connect them to Realme 8 Pro but headphones doesn't work. Despite fact that theadphones are connected to the USB-C, the sound is still heard from the phone's loudspeaker.
I turned on the OTG function, but it also didn't help.
There was not even an icon on the phone that the headphones are connected, nor any system message about the connected device
Has anyone similar problem and knows how to solve it?
I think, theres no solution. That headphones works only with Oppo device but not all of them...
(I checked it in store)
Strange
Go to settings/additional settings and Look for OTG switch. Unfortunely you have to check that box every time you connect headphones. At least it works for my setup - OTG adapter + senheisser earbuds..
