Your problem seems simular to what I had.
If you are sure the software settings are ok and that doesnt work, remove the backcover remove the battery connector, put it back again and see if that works. Does charging work?

Thats weird my s2 tablet has USb problems to. It stopped reading OTG usb connections and the PC. However it is always able to charge. I have noticed that when it does finally read on the PC it seems like the drives dont switch right and my battery wont charge. It got to the point I dont even try to plug it into a pc or USB otg just incase it quits charging I have SD card and twrp for installs so I use that instead. Most be a problem with the usb port and drivers.

I dont know the answer nor the solution.
What I noticed however is that I used my tablet as an monitor for an USB web cam.
The problem (charging but not being able to connect to PC) started AFTER I removed the webcam.
The app I use (USB Camera Pro) has an option "remove camera safely"
If I use that option everything works fine but if I remove the cam cable without pressing this option I cant connect to my PC anymore and have to unplug the battery.

I am having a similar issue and would be grateful for help. My Tab T815 has a clean install of the latest Android 10 Rom and Pico Gapps via TWRP 3.4. All seem to be working great apart from the USB OTG. Specifically, I am trying to connect my DJI Mini drone controller and it's not registering it plugged in. I also have Android 10 on a galaxy S5 and have no issues at all when I connect the DJI controller to the phone. I have run a diagnostic app that says OTG is compatible with the T815 so am now at a loss on what to try next. Could this be an issue with the Rom?
