You will need to reinstall the software drivers for your chipset. Check
Compaq's website (or is it HP now?) and see if there are updated drivers
for your computer. There should be new USB drivers that may be included
in other drivers as well. It is also possible that what you thought was
USB 1.0 was actually a USB 2.0 port that just didn't show up as that
because you did not have an OS that supported USB 2.0. Also, in a while
Service Pack 2 will be released and it is going to be a HUGE update. You
may want to try that as well. There is a technical preview of the
release candidate 2 available to the public for download.
