I have an internal cd-reader and a external DVD-writer from HP.
It seems that a /dev/ file is not created for the USB DVD-writer.
Here is the output when I connect the DVD writer:
$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[1513881.508050] add /devices/pci0000:00/0000:00:1a.7/usb1/1-5/1-5:1.0 (usb)

$ lsusb | grep Hewlett-Packard

Any advise? It worked in a old Fedora some years ago so I don’t think there is any hardware problem.
