I've installed a TSSTcorp CDDVDW SH-216AB Device on my PC (the only DVD drive).
Now I installed iTunes and it shows up the known Error Message
Die Registrierungseinträge für die iTunes-Treiber zum Import und Brennen von CDs und DVDs fehlen.
This means that the iTunes-Drivers for import and burning from CDs and DVDs are missing. My Problem with that is that my iPhone/iPad are not shown in iTunes.
Googling gave me the answer to add a Registry Item (Tutorial, German). I did so and it worked, the Message did not show up again. But I still cannot connect any iDevice with iTunes. Seeing the Device Manager in Windows, a warning sign gets shown at the TSSTcorp CDDVD Device. Removing the Registry Item and Re-Mounting the TSSTcorp Drive solves this problem - but then the Error Message on iTunes shows up again.
There must be an incompatibility or something with the CDDVD Drive and iTunes. Are there any commonly known solution for this problem? What should I do? I also followed all Steps on Apple Tutorials on how to make iPhones get shown in iTunes, didn't work either.
