I have 4 USB ports: 2 in the front of my desktop and 2 in
back. All worked perfectly about a year ago. Since that
time however, when I attempt to plug a new device into the
front ports, Windows starts the New Hardware wizard and
automatically loads an Unknown Device. There is no error
code next to the Unknown Device and the VID/PID identifier
is all zeros. If I try to uninstall the unknown device, it
comes back when I restart, "Scan for new hardware", or
plug a new deivce into those 2 ports. If I plug that same
new device into the back USB ports, Windows correctly
installs the proper driver. If I disable the unknown
device and plug in a new device, XP adds a second unknown
device. If I update the driver for the device, it appears
to copy the new driver, but the status says "no drivers
are installed". I have tried to reinstall XP, remove all
USB devices, disable non-essential startup programs, and
restart in safe mode - the following info shows in the

Could this be due to an install of an old hardware device
that I have since removed? I don't recall exactly when
this problem initially occurred, so it could be one of
several old devices. Any help with additional
troubleshooting would be greatly appreciated. I've
followed the Microsoft article "troubleshooting Unknown
Devices" and couldln't resolve.
