adding support for Edirol UA-101?

adding support for Edirol UA-101?

[Ákos Maróy]

Hi,

How difficult would it be to add support for the Edirol UA-101 external
USB audio device to the usb-audio driver?

I can see in ./sound/usb/usbquirks.h the comment:

    /* TODO: add Edirol UA-101 support */


and then I see sections there, which pretty much look like definitions
with the USB IDs & all.

would add support for this device be more than doing some elaborate
copy-paste-ology?


Akos

PS: sorry if the question is really lame..

This device uses high-speed (USB 2.0) transfers and a synchronization
mechanism that isn't covered by the USB Audio specification (that
specification was written before USB 2.0).

The existing infrastructure in the snd-usb-audio driver helps only
partially.  I have started writing a separate driver for this device
(and for the UA-1000 which is similar), but I won't have as much free
time as I'd like in the near future.
