Hello there,

I have contacted Tascam because of the us-1641. They had send me an answer
(in German):

"...Linux Treiber sind von unserer Seite her nicht geplant. Die Treiber
basieren aber auf einem identischen Konzept wie die des US-144.
Bisher wurde von Seitens des ALSA Projects keine bitte um, eine
Unterstützung für die Treiber Entwicklung des US-1641 an uns
Wir hatten einem hier in Deutschland ansässigen Teilnehmer des Projekt
bereits für die Entwicklung der US-122L und US-144 Treiber leihweise
Geräte als Entwicklungsgrundlage zur Verfügung gestellt und könnten uns
ähnliches auch in diesem Fall vorstellen. ..."

They said:
They don't planned any Linux-drivers. But the drivers are based on an
identical concept like the US-144. So far, the ALSA Project not asked for a
driver support for the development of the US 1641.
They hired an in Germany living developer an US-122L and an US144 for
developing a driver. In this case they think, they would do something like

I hope anyone helps this information.

Regards, Chris
