I have never understood USB listings in device manger in XP. It seems the list is growing while I continue to have problems with various USB devices. First one device doesn't work, then another, nothing predictable. Possibly due to the failed installs and then uninstalls of a printer.
I finally added a USB card which seems to be working except (and maybe this is normal) three USB are listed instead of five. The last entries which are for the card are now VIA Rev 5 or later USB Universal Host Controller, VIA Rev 5 or later USB Universal Host Controller, and VIA USB Enhanced Host Controller,. I tried to check which devices are linked to the USB Root Hub (seven of these listed) but I just see some generic information, no name. I have two USB Mass Storage Devices listed There is a listing for USB printing support, three Intel USB Universal Host Controllers, and an Intel USB 2.0 Enhanced Host Controller Can any of these be deleted? Would this help clean up the system and possibly get the USB devices to work all the time?
