experienced problems using external usb dvd drive

I checked it with my desktop ubuntu 14.04 box, so hardware is OK

Bus 002 Device 002: ID 14cd:6600 Super Top USB 2.0 IDE DEVICE

uname -r:

Code:

dmesg:

Code:

[  377.289460] usb 2-1: new high-speed USB device number 3 using ci_hdrc

the strange thing is that there is no mapping to /dev/sd* device

is there something missing in kernel???
