USB client and debug

I have installed the pre-release 2 and I have a Panda III card.
I would use the card as a USB client virtual serial port.
I tried the CDC example in documentation and I did not understand whether I can debug or not … in any case the line

Controller.ActiveDevice = vsp;

through an exception and with or without debugging prg can not continue.

… any idea?

@ coccoliso - When using USB client for something other than debugging, like CDC, you can only debug your program over the serial connection.

@ coccoliso - Invest in an FTDI cable.
