Tried that. The usb_get_report_desc() returns NULL. This is not a complicated device --- it's not even technically a "human interface" device.
I suppose I need to know how to supress uhid ... or to make ugen show up. It would also be nice to know how to generically poke the interupt enpoints...

I wanted to try to avoid that since I use many USB devices, but it's a last resort kind-of-thing.
The documentation for the device describes the interface as simply using the two interupt endpoints (read and write).
Dave.
