That doesn't tell me enough to know what you need to diagnose this
problem.
: usbconfig -u xxx -a yyy dump_curr_config_desc
: usbconfig -u xxx -a yyy dump_device_desc
How do I now the address? Is it the .Y in ugenX.Y?
If so, here's what you requested:

:
: Vendor ID, product ID, lower inclusive revision number, higher inclusive
: revision numer that is used when matching the quirk.
I'll give it a try...
