For those of you wondering, the USB to serial driver for the Vex programming modules (which will work with both prototypes and the commercial version) comes with the install of the EasyC software. EasyC software will come with the commercial version of the Vex programming kit. I don't know if it will be available stand-alone.
BTW, the EasyC software's name really means it. A little over 12 hours ago I knew
nothing about C, but in less than a few hours, I had been able to program a VEXbot with the Vex Ultrasonic sensor to navigate the room avoiding obstacles.
