I've seen a schematic for a USB board for the verdex 24-pin flex connector.  This is nice if you only need one port but has anyone been able to provide more than one interface with this connector?  I have a verdex-xm4 with robostix and netwifimicroSD.  I need to have 2 or more USB and/or RS232 interfaces.  I am not an electrical engineer so I could use some advice.
