This device doesn't seem to be supported yet. Does Roland make the
specifications available, etc? The device is not compatible with USB
Audio, but rather uses Vendor Specific Class. lsusb -vvv is attached
below and if you need more information, I can debug the device on Linux
and on Vista.

Repost, as I got no responses to the original.

This device doesn't seem to be supported yet. Does Roland make the
specifications available, etc? The device is not compatible with USB
Audio, but rather uses Vendor Specific Class. lsusb -vvv is attached
below and if you need more information, I can debug the device on Linux

The Roland/Edirol M-16DX is a digital mixer which can also function as a 
18 channel capture / 2 channel playback USB 2.0 interface. The device has 
been added to quirks-table.h and has been reported as working with one 
problem: when playing back there's severe audio distortion at regular 
intervals (several seconds), which has been traced to the fact that the 
device utilizes the IN endpoint as an implicit feedback channel; see the 
output from lsusb -vvv from a 7 year old post by Lasse Kärkkäinen below
