USB 2.0 on E420 ExpressCard34 connector pinout?

2014-10-23, 23:47 PM

I tried to install a SY-EXP15026 RS232C Serial Port card in my E420  with W7-64.  The install does not find the new hardware, as if there are no connections.  I tested card by wiring to a USB cable, and the card installed via plugNplay and worked properly when plugged into USB port.  The expansion bus is enabled in BIOS.


 My thinking is the USB 2.0 (pins 2 and 3 in EC34 standard) connections on the ExpressCard34 are not implemented on the E420 card slot.  I do not want to disect my E420 to find out.


Does anyone know for sure.
