Hi there, My first post! As the title says, I used my own copy of XP Pro to do a clean install on my Packard Bell laptop. Now my USB2 sockets have been downgraded to USB1. The PB site has a patch which apparently should fix this, however it won't run as I have installed service pack1, and the patch says SP1 should fix the problem. I Googled "Sis962 drivers" and found what I think I am looking for on another manufacturers website (computer specs look exactly the same as mine). Is it possible these drivers will work, they are for the same OS and chipset so I think they might. Also, is it possible to uninstall SP1 (perhaps system restore?) and see if I can run the patch? Many thanks in advance! Paul.
