Blu-Ray drive seems to be recognized as harddrive (/dev/sdb) (drive conntected at SATA -> USB adapter)

I have connected my Blu-Ray disk drive via a SATA -> USB adapter to my notebook. But is not found as optical disk drive by the system. When I type in

lsusb

it shows:

Bus 004 Device 005: ID 152d:0578 JMicron Technology Corp. / JMicron USA Technology Corp. JMS567 SATA 6Gb/s bridge

And when I do: dmesg | grep usb

I get this:

As far as I can see it is recognized as a hard disk drive. Is there a way on linux to change this or is it because of the adapter/ bridge and can not be changed? (In the last case I would of course purchase a new one. Anything I have to pay attention on?)
