USB error: "One of the USB devices attached to this hub has malfunctioned, and Windows does not reco

Ok, this is strange.

It's not a USB power error, at least as far as I can tell. And before
you ask, no, the system is not under warranty.

First, the config: I have a Dell Inspiron 700m laptop. It's been a
great little workhorse, but suddenly I'm having an issue with one of
the USB ports on the system. Specifically, when I attach ANY USB
device to one of the ports (of course, the USB 2.0 port, not the USB
1.1 port), I get the following error:

"One of the USB devices attached to this hub has malfunctioned, and
Windows does not recognize it."

This happens with any device I plug into the port. The other USB port
works fine, though. The same devices plugged into that port work just
peachy. In Device Manager, there are four Intel 82801DB/DBM host
controllers (one "Enhanced USB 2.0") and all four appear normal.

Has this USB port gone bad?

I had a simular problem at xmxas when i got a exturnal hard drive I had
to install the SIS usb drivers because somehow my system had started
using the windows xp usb drivers which were not compatable. also if
your computer is left plugged in to a power supply it will remember the
usb settings so it has to be turned off and the power lead removed for
about an hour to make it forget.

How this helps
