I have 3 DVDRW drives in my system. /dev/sr0 - AD-7173S /dev/sr1 - AD-7230S /dev/sr2 - AD-7230S K3b detects /dev/sr0 and /dev/sr2 If the AD-7173 is removed, only 1 drive is detected. If only one drive is installed, it is detected correctly (any of the 3) Swapping /dev/sr0 and /dev/sr1 around results in /dev/sr1 and /dev/sr2 being picked up. It appears the software is confused by multiple identical models and only shows the last detected one of each attached to the system.

Not sure why this is unconfirmed. I have the same problem, but looks like it is the way K3b is getting it's information from Udisks. I have 2 identical drives: Lite-ON Model LH-20A1S (both are sata) /dev/sr0 symlink of /dev/cdrom /dev/sr1 symlink of /dev/cdrom1 1) K3b only sees /dev/sr1 when both are installed. 2) K3b will see /dev/sr0 only if unplug /dev/sr1. It might be the way K3b gets it information from udisks. Udisks reports two ways: a) udi = '/org/freedesktop/UDisks2/drives/LITE_ON_DVDRW_LH_20A1S_LITE_ON_DVDRW_LH_20A1S 1) where it only report /dev/sr1 (maybe just the last drive it sees if both the same) 2) this way only looks at 'drives' b) '/org/freedesktop/UDisks2/block_devices/sr0' AND udi = '/org/freedesktop/UDisks2/block_devices/sr1' 1) where it reports both devices /dev/sr0 & /dev/sr1 2) this way looks at 'block_devices' c) Looks like K3b is only looking at udi = '/org/freedesktop/UDisks2/drives/ Also know that both drives are good. Have used /dev/sr0 with Xfburn, which sees both drives. Used with Xine, cdrecord,...
The problem appears to be due to optical devices reporting their model number in the scsi serial number field. Udisks doesn't like that and only reports the first one it sees. This is a consistent "error" across multiple optical drive makers, so udisks needs to cope.
Hi, k3b master https://github.com/KDE/k3b is able to detect multiple devices https://pbs.twimg.com/media/Cro8t4oUEAAonM2.jpg one is CDEmu and one is ASUS, if created more virtual devices by CDEmu, k3b is also able to detect them! so please try k3b master branch, if still unable to dectect, please let me know, thanks a lot! Regards, Leslie Zhai
Leslie: This bug can only be tested if you have 2 _identical_ drives. if you use a bunch of different models then they get picked up fine. I'll test this, but please bear the point above in mind. Thanks
Hi Stota, > This bug can only be tested if you have 2 _identical_ drives There are often /dev/sr0, /dev/sr1, /dev/srN for the multi-drivers of Real or Virtual device driver. But I will bear the point you mentioned in mind, and please test the master branch, thanks a lot ;-) Regards, Leslie Zhai
