For some years I've resisted using Service Pack 4 on my Win2K machine but, stemming from a recent re-formatting of my hard disk, I've now installed it. Trouble is, I'm having a problem installing my Epson flatbed scanner, which is USB2.0. The setup for the scanner's driver completes but when I then connect the scanner's USB cable, Windows fails to install it and I get an immediate re-boot. I didn't have this problem with SP3.
 
I do, of course, have the USB2.0 driver itself pre-installed, and other USB2.0 peroipherals of mine have installed fine, so it could well be a problem with the scanner's driver, rather than anything to do with the USB2.0 driver.
 
I've looked at the constituent USB2.0 files in my Win2K and they're:
 
USB Enhanced Host Controller v5.1.2600.0
PCI to USB Open Host Controller v5.0.2183.1
USB2.0 Root Hub v5.0.2195.6717
 
and their detailed files are all there in \system32 as well.
 
But have there been any known issues with SP4 and USB2.0? Could SP4 possibly have removed a critical constituent file of USB2.0, perhaps not shown now in Properties?
 
If not, I can be more confident that another Epson driver that I've found will install and work.
