Hi all,

I'm in the process of making a M-Audio Transit USB audio interface work
on NetBSD.

I can load firmware via DFU (Device Firmware Update), the device is
attached by the uaudio driver, but I can't play anything yet:

    $ audioplay -d /dev/sound2 -c 2 -P 16 -s 44100 -e slinear_le filename
    audioplay: failed to open /dev/sound2: Invalid argument

Suggestions, anyone?

Currently I'm testing on i386 1.6.2_STABLE and I will try 2.0_BETA
and/or -currrent once my laptop returns from its latest hardware repair.

Before firmware download:

    ugen0 at uhub0 port 2
    ugen0: Unknown Unknown, rev 1.00/1.00, addr 2

After the firmware is download and the device is reset:

    ugen0: at uhub0 port 2 (addr 2) disconnected
    ugen0 detached
    uaudio0 at uhub0 port 2 configuration 1 interface 0: M-Audio Transit USB, rev 1.10/1.00, addr 2
    uaudio0: ignored audio interface with 2 endpoints
    uaudio0: ignored audio interface with 2 endpoints
    uaudio0: ignored setting with type 8193 format
    uaudio0: ignored setting with type 8193 format
    uaudio0: audio rev 1.00
    uaudio0: 4 mixer controls
    audio2 at uaudio0: full duplex, independent
