Hello Marco,
I can't give you the exact solution, but I noticed that it doesn't work the same way everywhere.
On my PC with Windows 7, the part was recognised, but I couldn't install it. On my laptop with Windows 10, it worked straight away. In my opinion, however, the part is not worth its price. The quality is so poor that filming from the TV is even better :-( I will now have my videos scanned externally.
