Navigate to key HKLM\System\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318} if you find in this key phrases UpperFilter,LowerFilters ->remove them +restart.

FYI:
I think it is similar to famous DVD trouble Your CD drive or DVD drive is missing or is not recognized by Windows or other programs.I know it can't remove UpperFilter,LowerFilter for all kind of devices but I compared with my registry this key I can I sure I don't have UpperFilter,LowerFilter in this key also.So for this device is also appriopate procedure.
