USB ports are soldered to the motherboard. Typically the entire
motherboard is replaced. I have met people who can solder on new chips
but they did it for fun, not as a business.

By the way, do you have built-in wireless on your R40? If so, can you
type "lspci -nv > out.txt" and mail out.txt to me? I need to change the
ID on a wireless mini-pci NIC.
