[linux-audio-user] Gentoo and Tascam US-122 USB audio interface

[Tobiah]

I compiled support for my US-122 right into the kernel.  Gentoo
seems to have installed alsa-{lib,utils,tools} as dependancies
for other things.  It didn't install alsa-driver, but I would
guess that the kernel driver is enough.  Is that true?

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.

Information on USB audio seems fairly scarce out there.  I'm 
not sure what to do next.

Thanks,

Tobiah
