Re: AVMiu_MC Error

That happens because on some localized versions of Windows, the internal TSP name of the Generic TSP is different than what Unity is expecting. The Unity component that deals with TSP devices tries and fails with its expected name. When that happens, Unity will try no longer to open up other TAPI devices.

This has been fixed in future Unity versions that have not released yet, but there is a workaround that you can try. Open the Telephony control panel and remove the Generic TSP. If for whatever reason you really need the Generic TSP, it can be re-added. Re-adding the Generic TSP will add it to the Windows list of installed TSPs, but it will be after the Skinny TSP.
