I can't tell exactly what's happening, but your device is sending back a lot of error messages (Not Ready - Medium not present). Maybe it doesn't recognize the type of disc you have loaded.
Also, there appears to be some program querying the state of your device 7 or 8 times every two seconds. I can't tell what that is; it might be hal or it might be your k3b program.
However what finally caused the failure was a command (0xAC) which I don't recognize and apparently your drive doesn't recognize either.
