the usbcom+ cable goes from the esc to the computer and allows for programming ease. to connect this cable to the esc i think you have to unplug the esc line out of the receiver and plug that into the usbcom+. the cc o2 cable plugs into a port on the esc and the usbcom+ plugs into that so that unplugging the esc from the receiver isn't necessary. make sense? thats how mike explained it to me.
