Lately every time I try to connect a known working USB device, like digital camera, thumb drive, web cam, etc. I get a pop up window that says the device is not recognized. I have a printer plugged into a USB port, and it works, although I did have to reinstall the driver for it recently, because it too get the same error.
Is there a driver or drivers I should reload? What should I do to determine if it's really a hardware (port) problem? Devices will work on other computers, just not this Compaq desktop, 1.6Ghz, 2GB RAM, roughly 3 years old, XP SP3
