SBS 2008 usb drives reported as not recognized or malfunctioning....

I've a Proliant ML115 G5 running SBS2008, 4 GB RAM, Mirror RAID...

I backup to a USB 1TB drive which has worked fine for 6 or so months untill last week. The StorageCraft software suite reported it could not find the USB backup drive.
I have tested the drive on another machine and it works fine. The I tried a different USB drive on the server and that failed to be recognized! There does not appear to be any updates to drivers.

One thing I did notice is while was unistalling the USB controllers to re-install, I uninstalled the "Standard Enhanced PCI to USB Host Controller" the USB backup drive was recognized by the system, the system then reported that the device would run faster on a HIgh Speed USB Port!!!
When I reinstall the "Standard Enhanced PCI to USB Host Controller" the unrecognized device problem comes back.

Any ideas anyone?

Ian
