Have you checked that the USB support from your BIOS did not somehow become
disabled? If the USB ports are enabled, they should show up in your device
manager under "Universal Serial Bus Controllers". If there is nothing
there, this may be your problem.

Neither scenario is likely. USB devices draw power - they don't provide it,
so I doubt your camera could have damaged anything. If anything, your
camera would be damaged if something went wrong with the USB ports. SP2
might be the problem is the ports stopped working immediately following the
SP2 install. Otherwise, this is probably unlikely as well - particularly if
a PCI USB interface does function.

If USB is enabled in your BIOS, it's more likely that your USB on the
motherboard is bad or the header cables are loose/disconnected.
