WL500g with 2 usb ports

[wtzm]

Has any body considered adding a USB2 host controller too there wl500g?

I doubt that this would make much sense - even the Deluxe, which has a 200 MHz cpu, compared to 125 MHz on this unit, isn't able to transfer more than 2 or 3 MByte/s across the bus in typical situations (as Network Attached Storage e.g.).
