hello,my friends:

I have a problem when I try to program multiple device in sam_ba mode via usb;
exactly I try to program 2 chip in parallel;so I load sam_ba on both of them and then connect them to computer , fortunately sam_prog recognize them (active connection = 2)
but when I try to program chips("write flash") ,it causes a blue screen ;
in command line mode with sam_ba, I have the same problem with debug error instead of blue screen.

is it a driver problem,and how can I solve it;
is there any kind of other software or driver than I can use instead of sam_ba and sam_prog for programming via usb port and without any need for programmer hardware;

thanks a lot for your attention and response!
