can you open alsamixer on a console, and press F6, this will open a small window on the screen, where you can see the devices recognized by the system.

My Linux box too identifies my Scarlett 2i2 as a digital camera (that is generally just a description, wrong, but a description only), but it plays audio through it, nevertheless...
