Hi Bart,

Unfortunately, I'm unable to reproduce your findings.

This is what shows up in my dmesg output:

[  166.135611] usb 1-6: new high-speed USB device number 5 using xhci_hcd
[  166.272735] usb 1-6: New USB device found, idVendor=0e8d, idProduct=1887, bcdDevice= 0.00

[  167.616339] sr 2:0:0:0: Attached scsi generic sg0 type 5

Nothing strange, but when I do 'fdisk -l' nothing shows up. I'm not only unable to write, but also unable to read DVD's.

Regards,
Mischa.
