Post VEXnet 2.0 Upgrade Issue
I'm having trouble updating to the VEXnet 2.0.

After updating the VEXnet keys to 2.0 and the joystick firmwear and Cortex firmware and master firmware to 4.25 the joystick and Cortex appear to link on the tether (3 green joystick lights) but not with the keys (on joystick: "JOYSTICK" light green, "VEXnet" light flashing rapidly).

With the tether in place all programmed motors (RobotC sample programs loaded normally using tether) run for three seconds at Cortex turn-on but do not respond to joystick inputs. With or without VEXnet keys installed all programmed motors run continuously at Cortex turn-on.

All VEX updates were done on a Windows 7 PC on the school's network running RobotC 4.52.

What am I doing wrong?

Did you update the firmware for the keys? That is the new step that 2.0 keys require. Also just for clarity under robot is compiler mode set to usb and joystick?

Thanks for the response.

The keys are updated to key firmware version 1.46.

The communication mode was USB only.

Does changing the USB to not be USB only resolve the issue?
