hub 1-0:1.0: over-current change on port 2

When booting, after loading uhci-hcd successfully the message "hub 1-0:1.0:
over-current change on port 2" is echoed repeatedly and rapidly to the current
console, making the use of the system and completion of the installation
impossible. From my research and some help from people in the Ubuntu IRC channel
this appears to be a USB problem, perhaps at the kernel level. I have tried
booting with the flags "nousb" and "noacpi"; kernel is 2.6.8.1-2-386. I have a
Compaq Armada 100S. I saw a similar problem with the same notebook in RedHat 9
at: http://www.redhat.com/archives/fedora-list/2004-July/msg01307.html

I booted into Knoppix 3.4 and got the output to dmsg, lsmod, and lspci.

dmesg:
