Our team misplaced our orange VEX direct tether USB A-to-A cable (http://www.vexrobotics.com/276-1403.html), and I was thinking about ordering a cheaper one from Amazon rather than buying another marked-up one from VEX.
Do standard USB A-to-A cables do the trick for direct tethering and code transfer between computer and the Cortex, or is there some propriety hardware or firmware packed inside the official VEX ones that enable communication?
Thanks.
