This is your problem. Interrupts are not getting delivered.
Unfortunately this is not a USB or CPiA problem.

There's a couple of things you may want to try:
- Look in the BIOS for a "MPS Version" setting. Set it to the opposite
- Look in the BIOS for a "Assign USB Interrpt" setting. Set it to the
  opposite
- Upgrade your BIOS
- Send a message to linux-kernel or something similar.
