Hello all,
I know I am asking for trouble here :-) but what is it in the
USBAudio.sys driver or the USB Audio standards that does not serve your
needs? Why do you find it necessary to create your own drivers? The
reason I ask is that we are in the process of updating both the driver
and the specifications.
Thanks,

Somewhere else in the DDK it says that for USB sound devices you should
use a
standard USB device structure. If you doing it another way, you don't
get any
examples from MS. I needed some ugly hacking to get it done anyway.
