If you use the lsusb command from the usbutils package on this device you can
check its USB descriptors.
Look for:
AudioControl Interface Descriptor:
bLength 9
bDescriptorType 36
bDescriptorSubtype 1 (HEADER)
bcdADC 1.00
If bcdADC says something other than "1.00", I think you're out-of-luck.
I suspect it reads "2.00". AFAICT "Universal Serial Bus Device Class
Definition for Audio Devices Release 2.0" isn't supported by OpenBSD.
Unless someone else has a better solution, quite likely the uaudio driver will
need somebody able to update it for your device to work.
