I am running a Sony Vaio PCV-RS510 with MS XP Home Edition (SP2). About 3 weeks ago, my hard drive crapped out and I had it replaced. I used the Sony System Recovery disk and everything is working great now except that my 8 USB ports are now operating at low speed and they used to all be 2.0 and operated at hi-speed. I have uninstalled the host controllers and let XP reinstall them upon start-up. I still do not have the Enhanced host controller. I have talked to Sony, they recommended unistalling SP2, installing their SP2 patches and reinstalling SP2. I did all of that, still no results.
 
Can anyone give me some tips to recover my USB 2.0 capabilities?
 
Thanks
