The details here, say the chipset on pcv-RS602 is 865PE. And the Southbridge
of that chipset is ICH5, which is the chip I mentioned below. So you could well
have had a complete USB failure caused by static electricity. It is
not your fault - there is something wrong with the design of the chip,
that makes it weak. There is only one public admission of a problem, and
zero information from Intel about it.

You can check the details of your system, using CPUZ.

You can try installing a PCI USB2 card in the computer, to replace the
non-functional USB ports. That will not be sufficient to make a USB
keyboard work in the BIOS screens, and that is the only weakness of
using a PCI USB2 card as a repair. If you want to access the BIOS
screens, when your USB ports are broken, a PS/2 keyboard is best.
If the computer was under warranty, getting the ICH5 chip replaced would be
the thing to do. But at the moment, I think a lot of people with an
ICH5 on their motherboard (such as the computer I'm typing this on),
have no warranty left. In which case, buying a PCI USB2 card might
be the cheapest alternative.
