After you set this, did you reboot the system?

Could you get the debug infos from mdb as follows and send it to me?

#echo "::usba_clear_debug_buf" |mdb -wk
 then Plug in your usb device and wait several seconds
#echo "::usba_debug_buf" |mdb -k > /tmp/usblog
#echo "::prtusb" | mdb -k >> /tmp/usblog
#dmesg >> /tmp/usblog
#prtconf -D >> /tmp/usblog

Thanks
