I need high quality usb audio card for ubuntu 12.04 PCs so I bought Roland Duo-Capture which is very promising. the problem is that with:

cat /proc/asound/cards

I can see only the integrated audio card

0 snd_hda_intel

While issuing the

lsusb

I see the device:

Bus 004 Device 002: ID 0582:012b Roland Corp.

Is there a way to have ALSA understand this is an audio card? If there's no chance to have this usb audio card working on ubuntu, may I have a list of high quality usb audio cards which for sure are supported by ubuntu 12.04?

As seen here, flick the little switch on the bottom marked EXT from * to **. No idea what this means but the device will now be recognised and work in Ubuntu.
