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.
