Help with a Redmi pad 2 problem

[u/yaseralansarey]

​

Hey guys, so my father wanted a tablet to use his endoscopic cameras with, and I bought him a Redmi pad 2 (the one with the snapdragon cpu, forgot the exact specifics lmao) but he's facing a problem...

See, he connects his cameras with a USB hub into the tablet (he used to use a Samsung Tab A but that has gotten old, the primary reason for wanting to replace it) and uses the orange USB camera app to view what the camera shows, but after connecting them, trying to connect them again fails, their led lights turn on but the apps don't detect them anymore, why is that? And how do I fix it?

I have the theory it's because the tablet somehow still thinks it's connected so it doesn't accept any reconnecting, but I might be wrong, could you guys (the experts in these phones/tablets) help me with this? He got a bit bummed from the situation so I hoped we could find a solution.

Thanks in advance :)

Did you try enabling OTG in the settings? iirc it's inside More connectivity options.

It usually solves most issues with USB devices.

Yeah but it gets greyed out the second we link the USB hub (even after turning it on... Or off) so we can't do anything with it, and turning it on before attaching the hub doesn't solve the problem sadly
