Not sure if you're anti-linux but if you've got a computer magazine CD or
DVD with any flavour of linux on it (preferably Ubuntu, Knoppix or
SystemRescue) just boot your computer with the CD/DVD in it and also with
something plugged into the usb port.

Once linux is up and running just look for the terminal/konsole/command
line and type lsusb. The lsusb command lists the usb devices plugged into
your machine. It will will tell you if your usb port is alive or not. If
the usb device is recognized your problem is software-based.
