Try to turn on uaudio debugging in USB2 when you plug the device:
Dump the descriptors of your Audio device, if you have usbconfig installed. It
is not installed by default and it depends on libusb20. You can most easiliy
install usbconfig and libusb20 from my private SVN repository:
svn --username anonsvn --password anonsvn \
Goto the i4b/trunk/libusb20 and make all install
Goto the i4b/trunk/usbconfig and make all install
usbconfig -u xx -a xx dump_device_desc dump_curr_config_desc
One idea why your sound device does not work:
It has multiple configurations. You need perhaps to select config index 1:
usbconfig -u xx -a xx set_config 1
"xx" must be filled in properly of course.
This can be done automatically by the "add_dev_quirk_vplh" command. See the
UQ_CFG_INDEX_xxx quirks. You need to load "usb2_quirk" before it works.
You can also try loading "usb2_input_hid". Maybe it presents itself like a HID
device first, that's my guess.
