I am trying to use KDS 3.0 with a TWR-K70F120M and TWR-SER tower system.  I can't get the J-Link GDB server started.  I always get the "No emulators connected via USB" error.  I have two USB connections on the tower system, and they show up in the Windows 7 Device Mgr as OSBDM/OSJTAG - Debug Port (http://www.pemicro.com/osbdm) and OSBDM/OSJTAG - CDC Serial Port (http://www.pemicro.com/osbdm, http://www.pemircro.com/opensda).  I have worked through the user, quickstart, and troubleshooting guides, checked the jumpers, ran the P&E Firmware Updater utility, etc., but always get the same results.  Any ideas?

Hi Kirk,

If your board has the P&E OSJTAG firmware the you need to select the "PEMicro Interface Debugging" connection:

And make sure your board is detected:

Hope it helps!
