Ugh, in attempting to upgrade the driver in my WUSB54GS from 18.104.22.168 to 5.1.3538.0, I received an error message that the adapter could not be installed because the adapter's name "is already in use as either a service name or a service display name." Apparently, this is due to registry entries left behind in the removal of the adapter (I am running XP Home). Microsoft knowledge base article 823771 prescribes a fix that involves manually deleting the adapter's registry entries from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services. Does anyone know how the WUSB54GS's registry entries are named so I can know what I am deleting? Thanks!
