all usb drivers installed, as far as I know…
platform set on automatic
battery and power on…
still getting following error when I try to compile and download
“failed to verify that serial link connected to robot controller…”
I’m using a usb-usb cable to connect laptop to cortex.
any help appreciated!
Have you updated the firmware using the Firmware Updater Utility?
I think I may have tried to do the firmware update…
Can u tell me how to do this just so that I am sure…?
Which programming environment and version?
What is the laptop OS? (Windows 7 etc.)
Can you see the VEX robotics programming port as a COM device in the device manager?
Turn the cortex power off and attempt to connect.
When you plug the orange cable into the computer do you get a “found new hardware” message from windows?
Reinstall the USB drivers: http://www.vexrobotics.com/wiki/Software_Downloads
