Vista usb problems

Hi, my vista home premium upgraded itself and now I cannot use any usb ports. In device manager I see this...

When I try to update the drivers I see this...

I have tried to delete the file infcache.1 in the windows inf directory but this has not helped. I have also been repeatedly unable to install vista sp1, it goes through the whole process says it has done it successfully restarts and then rolls back the changes. Despite a long chat session with microsoft I can find no way of installing it. Any help really would be appreciated.

I tried using driver genius too. I installed the intel driver package it recommended but this only got so far and then said it had run into a problem and could not continue. So I reinstalled the back-ups.

Regards, Matt.

That sucks... Have you tried to delete each unknown device, then restart the computer and see if Windows is able to properly install the USB Controllers itself?

Well I found that if I uninstalled all these then it was able to reinstall them all properly. Weird. I hope this helps someone else.
