USB woes.

Hi

First off, I'm quite happy to be told that my chipset is old and
buggy and will never work (like the board's ACPI implimentation).
My USB doesn't work.  If I plug in a device (that works fine on my
other computer) and run 'usbdevs -v', I get the following:

[brane-dead] ~ # usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00
 port 1 powered
 port 2 addr 0 should never happen!

Followed shortly by this message on the console:

uhub0: device problem, disabling port 2

If I boot with the device attached, 'usbdevs -v' pauses for quite
a long time and gives the correct probe line:

[brane-dead] ~ # usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00
 port 1 powered
 port 2 addr 2: full speed, power 500 mA, config 1, Flash Reader(0xa600), DATAFAB(0x07c4), rev 1.19

However, the device is still unusable.

The hardware is:

uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0xe000-0xe01f irq 10 at device 7.2 on pci0
uhci0: [GIANT-LOCKED]
usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered

Do any of the USB gurus have any ideas?
