Cortex won't connect

I can’t get my cortex to connect to my computer. We had it connected then it unconnected and won’t connect. I tried to use an A to A cable. I also tried different communication modes. It won’t let me update the firmware. Do you have any suggestions?


Make sure the cortex is appearing in the device manager as a COM port.
Perhaps reinstall the drivers, try connecting with the cortex powered by a battery as well as the USB cord, sometimes using a USB hub can help.

If none of this helps then open a support ticket with us here.
