What type of computer is it? Is there any USB ports that work? Do you even
have one USB device that works such as a mouse? USB devices are a pain
sometimes. On some of the old Compaqs the USB functionality was hit and miss
just because they sucked.
Hardware failure is always a possibility in any given situation, but it is
hard to say that is what is happening in this situation. Hardware failure or
"something popping inside" is kind of tricky to troubleshoot via newsgroup
posts. I assume you tried all of the ports and multiple USB devices. When
you plug a USB device into the computer also check device manager to see if
that device shows up there. You could try removing all of your USB entries
in device manager and reboot the computer. When they get reinstalled you
could try the USB devices again.
