But the readout below contains the line:
"Mar 3 19:20:09 localhost kernel: Alternate Setting: 1"
I'm beginning to smell a rat in my hardware. I'm using a PCI -> USB
convertor card (my BIOS has no legacy USB support) which I have
never tried with any other USB device. To be honest, I don't own or
have access to any other USB devices, but I'm tempted to go out
and buy a cheap USB mouse just to find out once and for all whether
my USB interface is actually faulty.

Is this what you're after?
