requoting my original quote..

Can I add other USB peripherals ?
Not currently. It is intended in due course to support various other peripherals. The schedule or types has not been announced yet, but this might include any USB device such as webcams, printers, analogue modems, ISDN TAs, VOIP devices, bluetooth or Ethernet802.11b adaptors etc.

I can't see what use a ethernet switch that can control a printer would be if you can't send info to the printer.
and get print status and info back.
