Ok, another try. Details:
root@kg-v7# uname -a
FreeBSD kg-v7.kg4.no 8.2-STABLE FreeBSD 8.2-STABLE #6: Sat Jul  2 18:39:45 CEST 2011     root@kg-v7.kg4.no:/usr/obj/usr/src/sys/GENERIC  amd64

ugen0.3: <product 0x0901 vendor 0xc000> at usbus0, cfg=255 md=HOST spd=LOW (1.5Mbps) pwr=ON


I'm doing usbdump like this (inside a script(1) seseion, so I can get the output): usbdump -i usbus0 -vvvv -s 16384
Here is the output for usbus0.3:
