As per subject really. I have 4 USB controllers, with only 1 working. They either don't work or even block my USB keyboard from working?
Generic Chinese NES pad - Not working
Generic Chinese SNES pad - Not working
Speedlink Competition Pro - Not working
Datel Arcade Stick (has PS3/PC & X360 modes) - works
These controllers work on Raspberry Pi. Is there anything forum members can do to improve the Firmware's compatibility?
