Hi,

I am running Ubuntu 12.04 on my Dell XPS M1530. My cd/dvd combo drive is not being recognized. When I insert a dvd, the drive spins up and then stops.

The weird thing is if I then suspend the computer and wake it up, the drive is recognized (as /dev/sr0) and the dvd is mounted.

This is the output from lshw before and after the suspend/resume operation:

This is a dual-boot system and the drive works flawlessly on Windows 7.

For now I can make do with the workaround of suspending and waking the computer, but it would be nice to make it work without having to do this.

thx,

PS: I've searched the forums and spent the last week trying all the fixes suggested in various bug reports even remotely sounding like this issue, without any success. I'm at my wits end, and finally decided to ask you guys before finally giving up.
