I have been contacted by many who have bought the USB Audio 2.0 Reference card or is thinking about buying it.
Most people seems to have trouble getting started writing code for it - and very few just bought it to only have it as a standard stereo USB-soundcard.
It doesn't have buffered outputs so you cannot even connect headphones to it and listen to music, since the CODEC output should not be loaded below 10 kOhms - at least not under 3 kOhms.
I hereby start this group to make it easier to share knowledge around the card and the software.
So if you have the card or if you are thinking of buing one - welcome to this group!
