I upgraded that
form serial to usb connection
but my problem is that
when i am tring to send data to the controller then the profiller says
Error on opening comport #
when the comport is a serial hardware comport there is no problem
but on usb i have that problem
and from 2.0 and 2.1 version
i have test it from 3pc's Xp vista and 7
i dont think that is a hardware error
because on my previous cluster
there where no problem and everything was ok
thanks a lot
