The usbconfig is more than enough.

The easiest way would be to create a devd config file:
cat << EOF > /usr/local/etc/devd/myusbdevice.conf
notify 100 {
match "system" "USB";
match "subsystem" "DEVICE";
match "type" "ATTACH";
match "vendor" "0x0000";
match "product" "0x0000";
action "usbconfig -d $cdev set_config 1"
};
EOF
/etc/rc.d/devd restart
The "vendor" is idVendor and "product" is idProduct. See output from this
command:
usbconfig -d X.Y dump_device_desc
--HPS
