[alsa-devel] help needed: support of Tascam us 1641 usb 2.0 with support provided from company (was: [Alsa-devel] Tascam us 1641 usb 2.0)

[Sorry for the double posts you guys in CC. I got the wrong list address the first time.]

Dear ALSA developers,

Christoph sent the following message to alsa-user. Maybe someone can
step up to this task or at least tell how much work this will be. It
looks like, Karten wrote the support for the other Tascam devices.

        commit 030a07e441296c372f946cd4065b5d831d8dc40c

            ALSA: Add USB US122L driver

            Added a new US122L usb-audio driver.  This driver works together with a
            dedicated alsa-lib plugin.

@Christoph: I got this, cloning the Linux kernel tree and running the
following.

	git log sound/usb/usx2y/us122l.c

Thanks,

Paul

PS: Sorry for top posting, but I think in this case it is feasible,
because I changed the lists.
