Are you sure that it is a switch, and not a router/server?
The USB storage stinks here.

A LAN switch/firewall very probably uses a VLAN capable physical
interface chip internally, but it usually does not allow you to
define the virtual LANs associated to the cable ports. Please post
the make and model of the box, so we can check it.

Have a look at e.g. Zyxel gs-1200 series switches. The manuals
are available from the Net.
