I recently bought a USB adapter to use with my Ps2 controller and did some testing in lakka.
When I plug a USB keyboard into the laptop and launch some game, the keyboard and joystick stop working and I have to turn off the PC holding the button.
This only happens using the udev driver, I tested using HID and it worked fine. I wish someone would tell me what may be causing this problem
Extra question : Can HID support rumble??
