I have 2 Xbox Wireless gamepads, which I use with USB cables (I don't have the receivers at the moment). Everything was working fine until now. Didn't use them for a few weeks and now the PC just does not react in any manner to connecting them.
The only thing that happens is a controller vibrates when connected, but even the white lamp in the middle does not light up at all. There is no device connected/disconnected sound when I plug any of them in any port (I have tried all USB ports on the PC and external USB hub) and I could not find them being detected as anything in the device manager either.
Struggling for a couple days now -- I don't even have an entry point to fix the problem since the system just ignores the existence of the controllers. Other USB devices don't seem to cause any trouble on this PC and the controllers work well on another PC.
