Widcomm bluetooth driver and device not recognized after SP2 and SP3 - Solution
I followed many threads - only a few were aiding me but none helped. The problem, to summarize, is that SP2 provides windows with a list of generic bluetooth drivers. The original Widcomm driver is not signed or authorized or recognized as official (whatever...) by Windows and Microsoft. SP2 installs system information files in the %WINDIR%\inf (typically C:\Windows\inf) directory, which are then compiled into binary (.PNF) files which tell windows which drivers to load. Widcomm is not one of them.
Once SP2 installed the bth.inf and related bthXXX.inf files under this folder, and the system was rebooted, this information (I am guessing here) is loaded to the registry and is virtually impossible to revert without tampering with the OS functioning properly. (Don't try it, take my word for it, unless you'd like to spend days of recovering and re-installations). My solution is to reinstall SP2, but prior to re-booting, rename all the bthXXX.inf files to bth.inf.old.
