Add an external HD to NOKIA Model Number BGW320-505 gateway

Just to expand on @browndk26 's post above. The USB port on the two BGW320 models don't have the USB port enabled for Customer use. You would need to add a secondary switch or router that supports direct USB connection. 

You could also purchase a NAS that has an Ethernet or even a Wi-FI connection to allow direct access / usage by the BGW320s.

The USB port is for internal support use only.
