A data DVD in the DVD drive: **************************** ... Dec 26 09:40:45 eurit kernel: cdrom: Use count for "/dev/sr0" now 1
A data cd in the CD-RW drive: ***************************** ... Dec 26 09:44:49 eurit kernel: cdrom: Use count for "/dev/sr1" now 1
So your symbolic links should be /dev/dvd -> /dev/sr0 /dev/cdrecorder -> /dev/sr1
An audio-cd in both drives gave no debugging results, but I could not start it using kscd.
If you want to investigate the problem then you can run strace -o strace.out kscd and search the produced file strace.out for the file descriptor used for accessing the device: open("/dev/cdrom", O_RDONLY|O_NONBLOCK) = 8 select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout) ioctl(8, 0x5305, 0xbfffebba) = 0 ioctl(8, 0x5306, 0xbfffebb0) = 0 It's 8 in my case. The CD unit is controlled via ioctl calls (e.g. 0x5305), their values are described in ioctl_list(2) and /usr/include/linux/cdrom.h. -- Alexandr.Malusek@imv.liu.se
