VID and PID is fair enough. now what i want is that i have a threaded code that threads two functions to run at the same time. i want each function to run seperate devices. the problem is if it doesnt identify the attached devices it might run the code on a single device which isnt what is required. how will i be able to run a code on a device of my choice???....you can leave away the threading part for now. -- http://mail.python.org/mailman/listinfo/python-list
