Had the same problem and this was the trick that worked for me
Make sure to backup this registry settings first !!!
Remove the Upperfilters and Lowerfilters values completely from the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
Click Start, Run and enter REGEDIT Go to the branch indicated above, locate the Upperfilters and Lowerfilters values. Right click each and select Delete.
