The new USB stack has got a new uaudio driver also. I would try that first.

How to get the latest sources:

svn --username anonsvn --password anonsvn \
      checkout svn://svn.turbocat.net/i4b
#
# The following commands will
# install the driver on FreeBSD:
#
cd i4b/trunk/i4b/FreeBSD.usb
make S=../src package
make install

Then edit the file "install_uaudio.sh" and change it as needed, if you are
not 
installing to /usr/src.

./install_uaudio.sh

I am not sure what patches they MFC'ed from head to 6.2 release, regarding
the 
sound system, so it might be that my "uaudio.c" won't compile. But that can 
easily be fixed if you send me the compile log where it breaks.

--HPS

Thanks.
I did what you told me, but when I compile the kernel, it crashes compiling
umass.c (Don't know how it is related ?)

When I did "make install" it merged a lot of things in my /usr/src/sys, not
only audio... Is that normal ?
