The M-Audio MobilePre/Sonica/Transit/Ozone devices need a firmware
download before they can be used with Linux.
I've released a first beta of the madfu-firmware package which tries
to accomplish this.
Please note that I do not have any of these devices, and that the
loader is not tested at all. That's why I'm searching for volunteers.
:-)
To download the beta, go to
http://sourceforge.net/project/showfiles.php?group_id=87777&release_id=…
Please send any success/failure reports to
usb-midi-fw-user(a)lists.sf.net
Regards,
Clemens
