Ok, here's a toughy for you. This is someone's chance to show off.
I'm using a Gigabyte p55a-ud3 motherboard, which comes with about a million USB slots. This means that almost every IRQ is sharing with at least one USB port, including my graphics and sound cards etc.
Obviously I don't want my mouse to be sharing with my 5750, so how can I tell? In my sys info they are labelled 3B34 through 3B3F, but those number's aren't referred to by my mobo manual.
In the device manager, they don't show up. My mouse does, but I can't see it say anywhere which one it is plugged into.
In the BIOS, I can disable the USB functions entirely, but don't seem to be able to switch any individual controller on or off.
Does anyone have any ideas? I can't turn them off, and I can't tell if they are sharing.
