The gamepad is more or less a clone of a xbox controller (IIRC it is even from the same manufacturer), labeled PCPADRFLX.
lsusb lists the receiver as
dmesg | grep input reads
[6880.468415] input: ACRUX RF USB GAMEPAD 8206 as /devices/pci0000:00/0000:00:10.1/usb2/2-2/2-2.3/2-2.3:1.0/input/input17
Unfortunately, while the receiver is recognized, the gamepad itself does not connect. Usually after pressing a button on it the LED would light up once to indicate it has connected, however it just blinks as it does when no receiver is connected at all.
So, how can I make the gamepad work?
