[alsa-devel] Roland/Edirol M-16DX

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
and on Vista.
