Both internal optical drives on Mac Pro (summer 2010) not recognized after clean install of Yosemite 10.10.3. Both worked fine in Mavericks.

Both internal optical drives on Mac Pro (summer 2010 model) not recognized after clean install of Yosemite 10.10.3. Both drives work fine in Mavericks. Drives are Apple's Super Drive and Pioneer's Blu-Ray latest version in 2014. When I contacted Pioneer they said the drive will function with a generic driver. No issues prior to Yosemite. I have my Apple included system drive partitioned in 3, for Snow Leopard, Mavericks, and now Yosemite.

Whenever I hit the eject button or Alt-Eject neither drive opens and a pop-up window asks what I want to do with the disk just inserted. In neither drive was any disk even inserted.

The reason I installed Yosemite was to run the latest versions of Final Cut Pro (10.2), Motion, and Compressor which requires Yosemite. I'm also running Logic Pro X (10.1.1). I hope Apple isn't plotting to do away with optical drives.
