Hi,

attached patches implement a simple driver for the tascam us-122l.
Everything except midi out works i think ;-)

For USB 2.0 you also have to aply
	http://marc.info/?l=linux-usb-devel&m=119444869917392&w=2
named "ehci-hcd: complete iso urbs ASAP ..."

Will post a jack driver to use it soon.
so far you can #define DEBUG_USB_STREAM in usb_stream.c to 
playback what is captured.

no alsa pcm interface there yet. only a hwdep to talk to the
"usb stream" thing.

A userspace plugin that works like the jack driver would be fine too.
Is that easy to do? I mean that userspace driver should export all 
those standard alsa pcm interfaces then.

Comments bug/success reports, patches welcome.
