On the computer i just replaced the USB ports all slowly died, not too sure why but one by one they failed.Try plugging a USB stick or something else in the port and see if it is working, if it is I would delete all printer info on your computer and do a reinstall with new drivers, make sure you have the current service pack on your system...
