Ok, I looked into this a little bit further...
K3B provides an interesting log:
first, this is repeated 3 times:
(K3bDevice::ScsiCommand) failed: command: MODE SELECT (55) errorcode: 70 sense key: ILLEGAL REQUEST (5) asc: 26 ascq: 0
then it shows:
(K3bDevice::ScsiCommand) failed: command: GET PERFORMANCE (ac) errorcode: 0 sense key: NO SENSE (2) asc: 0 ascq: 0 (K3bDevice::Device) /dev/scd0: GET PERFORMANCE length det failed.
And then all commands from then on fail
strace indicate this is sent via SG_IO IOCTL (unfortunatelly, strace doen't show the contents in the ioctl)
I don't know if the device is supposed to stop working when receiving an unkown command (like it is apparently doing), also because apparently cdrecord doesn't send this command but fails anyway
