On the plus side I was able to use the uca-202 on my ipad to record from vinyl and then transfer over to MorphOS via FTP for conversion to flac and copy to audio player. This will have to do until MorphOS can handle a simple 2x2 audio interface for direct recording. (playback seems to be working already) I guess no one bothered to update usbaudio class since isochronous transfers were not enabled until now.
