Sorry, there seems to be a little incompatibility issue. You need to add:

#define USBD_SHORT_XFER_OK 0x0002 /* allow short reads */

to /sys/dev/usb2/usb.h

Then cd /usr/src/include && make install

Then recompile your software. Maybe I should keep USBD_SHORT_XFER_OK at the 
old value so upgrading won't be a problem ?
Hope this helps.

The ugen driver at /sys/dev/usb2/_ugen.c have a maximum length limit!
