[alsa-devel] [PATCH 1/1] sound/usb: Added support for Roland UM-ONE midi-usb interface.

[Daniele Guerrieri]

Hi all,
this is my first post to this list.
Recently i bought a roland UM-ONE midi-usb interface which i thought worked
well with alsa, but it didn't. So i got from lsusb id/vid and added them to
sound/usb/quirks-table.h; it seems to work well now with snd-usb-audio,
tested on 2 machines. Below there is the patch output for my changes. As a
master branch i cloned   git://github.com/torvalds/linux.git



----output of git format-patch -----

Roland UM-ONE midi usb interface differs from Roland UM-1.
