Choosing which USB port to connect with TCL script

I did a TCL script to program the FPGA (Spartan-3E) and to read some values using ChipScope VIO. Everything works fine.

The problem is that when I have two FPGAs connected to my PC, I can't choose wich one to connect too.

 

I do the connection using:

set handle [csejtag_session create "jtagWriteMessage"]
csejtag_session send_message $handle $CSE_MSG_INFO "Cable opened successfully.\n"

etc.

 

I don't have JTAG cable, I'm using the regular USB cable, and I tried with "CSEJTAG_TARGET_PLATFORMUSB" and specifying the USB port, but of course it doesn't work since I don't have a Platform USB Cable.

 

Is there a workaround?

 

Thanks,

Pierpaolo

Resolved using this: http://forums.xilinx.com/t5/3rd-Party-Other-Boards-and-Kits/Using-multiple-Digilent-USB-JTAG-cables-with-iMPACT-Analyzer/td-p/309551

 

Now I wonder if there is some way yo obtain all the serial numbers of the connected FPGAs.
