Repost...
As a followup, I modified the /usr/src/sys/dev/usb/ugen.c source to
provide some additional debugging output in the ugen_set_config() function
(relevant code at bottom). This is the code responsible for creating the
device structure for the USB device endpoints after retrieving the
endpoint addresses from the USB device (i.e. /dev/ugen0.EE). The
make_dev(9) call fails (see log entries below) with a non zero status.
Given the endpoints returned by the device were valid, I'm at a loss as to
why. The device works correctly under Windows 2000 (fyi). Is this a
problem with the my device, a bug, or ???

Initially I tried to use the uhid driver, but due to lack of functionality
needed in this case I removed the uhid driver from the kernel in favor of
the ugen driver. The ugen driver
