I compiled support for my US-122 right into the
kernel.
as module?
Gentoo
seems to have installed alsa-{lib,utils,tools} as dependancies
for other things.
guess that the kernel driver is enough. Is that true?
yes. You only need external ALSA drivers if you want to install very
recent versions of the drivers.
lspci shows:
Bus 001 Device 002: ID 1604:8006 Tascam US-122 Audio/Midi Interface
without fw)
But I don't get a device for the unit, and the USB light on the unit
does not light up, although the power light does.
I'm not familiar with this device, but is ALSA running and is the module
loaded?
/etc/init.d/alsa start
modprobe snd-usb-usx2y nrpacks=1
Information on USB audio seems fairly scarce out
there. I'm
not sure what to do next.
For other USB-audio-devices it's just as simple as modprobe
snd_usb_audio and you're done. AFAIK the Tascam additionally needs to
load a firmware:
emerge media-sound/alsa-firmware
vi /etc/modules.d/alsa
[...]
alias snd-card-1 snd-usb-usx2y nrpacks=1
Best regards
