Problem communicating with Cortex over both USB and Vexnet

  1. 8 months ago

    We have a Cortex controller that cannot communicate with the computer being used to program the device. We cannot even update any of the firmware as the comms link is not recognized by the computer. Any suggestions? Has anyone seen this problem before?

    We recommend to re-install the programming driver found here:
