K60 + TWR-SER USB echo demo doesn't work

I'm trying to get the USB_device demo working with a K60 and a TWR-SER.  The documentation suggests that it is just a simple echo through a COM port.

 

Do I need to connect USB cables to both the K60 board and the TWR-SER board?

 

I have tried various different jumper settings and can't seem to make anything work.  I'm using Windows XP.  I seem to either be able to get to where Windows only see's the OSJTAG USB device or it gives me the error message: "USB Device Not Recognized.  One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.  For assistance in solving this problem, click this message."

 

I try to then install the driver supplied with the demo (Freescale_CDC_Driver_Kinetis.inf) but it won't let me install that.

 

Any hints on getting this working?
