Hi

Hardware is:

uhci0_at_pci0:7:2: class=0x0c0300 card=0x00000000 chip=0x71128086 rev=0x01 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82371AB/EB/MB PIIX4/4E/4M USB Interface'
    class      = serial bus
    subclass   = USB

The system is CURRENT, about a week old.

It's generating a storm at ~76000 interrupts per second.  Is there
anything I can do to stop this?

The good news is that USB on this system works, previously it would
disable the port after a second or so.

Ian
