I'm resending this mail from a different address because last time it
was marked as SPAM.
I have a Roland UA-55 usb 2.0 soundcard that I would like to get
working on AV Linux 6.0. Right now it is not recognized by ALSA, but it
is recognized in lsusb.
Is anyone currently working on a patch? If so, I'd like to help as much
as I can. I'm willing to test out the patch on my system, etc. A
helpful person on linux musicians told me to contact Clemens via this
list. One of the AV Linux developers wants to try adding a patch to the
next kernel build (if one exists). If Clemens or anyone else is working
on a UA-55 patch, please contact me.
Here are a few relevant forums threads that I started:

Here is some info from my computer with the UA-55 plugged in:
