Doesn't recognize CD-R/Ws since Edgy

Thanks for your bug report.
Can't confirm this since CD-Rs and CD-RWs are detected without problems on my Edgy system.
We need more information, could you please follow the steps in https://wiki.ubuntu.com/DebuggingRemovableDevices and provide the necessary information.

This problem persists even in a fresh feisty install. Still volume.disc.type is "unknown" for my TEAC CD-W54E when I insert a CD-R whereas for my NU DVDRW DDW-061 hal recognizes DVD+Rs correctly as dvd_plus_r. Also hal doesn't give the volume a volume.disc.capacity key. I'll attach the debugging inf o from feisty.
