Message-ID: <82ecf08e0809040509v323a3065h68a2e72dc86f23ac@mail.gmail.com> (raw)

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
