In your previous mail, the device appeared as:
> uaudio0: class v2, high-speed, async, channels: 2 play, 0 rec, 3 ctls
Different class, different speed, different sync mode, which
corresponds to a very different device. This is very surprising to me.
Could you try to figure-out what makes this difference? (ex. try
different USB ports/hubs, tweak switches if any, plug/unplug audio
jacks, reboot with the device plugged/unplugged, etc).
Then, make it attach as "high-speed" and send me the resulting dmesg.

These strings are very strange as well.
