External DVD not seen

I installed a new LG GSA-H22N in a USB2 external enclosure. Power and USB cable - no problem.
The computer only sees it as a “mass storage device”, not as a DVD burner. None of my burning software (ImgBurn and Nero) can see it either.
I’m sure I’m missing something. Hope its simple :slight_smile: !
What are the “steps” to installing an external DVD burner?

Maybe it’s a problem with the chipset in the enclosure. You might want to take a look at the big external enclosures thread.

Maybe it needs to jumpered differently?
