I have 2 USB to SNES gamepad adapters, which were working well until a few days ago. Now the controllers are either not doing anything or will constantly scroll left on the EmulationStation menu. For some reason if I boot up the Pi without the USB wireless adapter plugged in, the controllers work fine. There have been no software changes recently, but just in case I restored the SD card from my last back up, which did not help. Has anyone else encountered something similar?
