Uninstall and reinstall ver1.1 and the update should then install 
without any problem.

I could not get SP3 to complete an install until I had to replace a HD 
and do a fresh install of XP followed immediately by all updates 
including SP3 before installing anything else. No problem with the 
installation and everything is OK since then. I had the CD's for SP2 and 
SP3 so it was easy and relatively fast.

In Device Manager, I have one enhanced USB with the driver dated 6/02 
and I have four standard USB with the drivers dated 7/01. If this is 
what you are referring to, then I do not think SP3 had anything to do 
with it based on the fact that they are not all enhanced and that the 
drivers are prior to SP3. Since I do not know the operational 
differences between enhanced and standard USB, I can't delve any further 
into your question.
