any change in usb status?

any change in usb status?

[Reynald Hoskinson]

I'm eying the maudio USB Audio Duo.  It seems an ideal soundcard for my 
needs, is locally available, and relatively inexpensive, and if I ever 
get a laptop, it'll work with that too. I understand usb is not 
supported by alsa yet. Is this still true? Is there plans for the 
future, or is there something that makes it impossible ever to use with 
alsa? The m-audio delta series is well supported, so perhaps this could 
be too in the future?

as i noted the other day, i believe that the plan is to support USB
(and IEEE1394/firewire) entirely in user space, though with the help
of the existing (generic) USB/IEEE1394 drivers.

alsa-lib has been designed to support such things. you just write a
library that opens the relevant USB device, handles the protocol
translation, and provides the functions used by alsa-lib. there is no
need to write a kernel driver. however, i have not heard of any plans
by anyone to do this. its not that hard in theory, but the impression
i have is that very few USB devices are fully standards-compliant, so
there is kinds of futzing around to get the device-specific parts of
the protocol translation part to work 100%.
