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

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.
