USB Cable Not Detected

port drivers and rebooting, the incorrect USB driver may have been installed. This usually occurs if you attach the
board to your PC prior to installing the Lattice-supplied USB driver.

For Diamond software and standalone Diamond Programmer:
1. Start Diamond or Diamond Programmer and choose Help.
2. Search for USB driver or Troubleshooting, then select the Troubleshooting the USB Driver topic.
3. Follow the directions to install the Lattice USB driver.
