Ok, here are the new results. I've decided to include most of the
output as attached files. Figured it would be easier this way for most
people.
The tests were done with the cvs tree from around 14:30EST with your
test define included in the usbmixer code. Included are:
lsusb-out.txt: lsusb -vv -s 1:4
sys-out.txt: syslog text when initializing default alsa drivers
proc-stream0.txt: stream0 contents (only stream file available)
alsactl-store-out.txt: syslog text when doing a alsactl store
As always, need anything else and I'll be more than happy to
provide. Sorry about the slow reply today, Mondays are full of
meetings.
