Worked perfectly for me in 10.3.1 on my TDK321040B (tested in iPhoto and Disc Utility) using:
<key>DRDeviceProductName</key>
<string>CDRW321040B</string>
<key>DRDeviceVendorName</key>
<string>TDK</string>

and naming the file TDKCDRW321040B.drprofile.

Thanks!

Dear all,

After several attempts based on your own experiences, I finally succeeded to activate the Superdrive Matshita UJ815-A on Panther that I installed on my Powerbook G4 Titanium 500Mhz.

I had previously upgraded it using the Powerbook Superdrive Firmware Upgrade provided by , thanks to him, and activated in OS 10.2 through the trick of AirForceRed, thanks to him to. But everything failed after installation of Panther as everybody knows…

The clue came from a search in Yahoo with "UJ-815 and panther":

http://search.yahoo.com/search?x=wrt&p=UJ-815+and+panther&n=20&fl=0

where I found the site http://www.partizan-media.com/Cube/dvd/ who had already succeeded the activation by replacing the full folder ~/System/Libary/Frameworks/DiscRecording.framework by a new one that you can load through its site. Many thanks to him (Boris).

I did it using OS9 to avoid authorization problems, but with a minor modification of the file DeviceSupport.drprofile (using TexEdit), changing

DRDeviceProductName
