i'm trying to get my external sound card to work with linux.
It is called Swissonic easy usb.

Output of lsusb:
Bus 004 Device 003: ID 152d:2539 JMicron Technology Corp. / JMicron USA Technology Corp. 
Bus 003 Device 003: ID 170b:0020 Swissonic
So it is there.

When i try to find a driver with `hwinfo --sound`, the external sound card is not displayed, just the onboard one.

I tried out all 'usb' drivers with 'snd' but the device is still not in 'proc/asound/cards'.

Maybe someone knows a driver i could try.

I also tried to find one on the internet, but there seems to be nothing there.
