Hi,

Can you list the configuration descriptor:

usbconfig -d X.Y dump_curr_config_desc

And also list all /dev/ugen nodes. Also note that starting from FreeBSD 8, you 
need to do some IOCTL's to set buffer sizes and such to get things working 
properly.

See:

http://svnweb.freebsd.org/base/head/usr.sbin/uathload/uathload.c?view=log

As a reference for simple BULK endpoint programming.
