[alsa-devel] [PATCH] snd-usb-us122l: added support for US-144

[Tobias Hansen]

Hi,

here is a patch that adds support for the Tascam US-144 to 
snd-usb-us122l when uhci-hcd is used (ehci-hcd has to be disabled). With 
ehci-hcd the US-144 behaves completely differently.

The difference between US-122L and US-144 on uhci-hcd is, that US-144 
uses endpoints on two interfaces, while on US-122L all endpoints are on 
one interface. US-122L should still work, but I don't have a US-122L to 
test that.

Audio in and out and Midi in were tested with US-144 and work.

This is my first contribution to the linux kernel, so please have a 
critical look on it. ;)

Taken against snd-usb-us122l 0.5 / alsa 1.0.20.

Regards,
Tobias Hansen
