Appendix A. Troubleshooting the USB Driver Installation
It is essential that you install the drivers before connecting your PC to the USB cable. If the cable is connected before
installing the drivers, Windows will try to install its own drivers that may not work.
If you have attempted to connect the PC to the USB cable without first installing the appropriate drivers, or have
trouble communicating with the Lattice USB cable after installing the drivers, follow the steps below:
Plug in the Lattice USB cable. Choose Start > Settings > Control Panel > System.
In the System Properties dialog box, click the Hardware tab and Device Manager button. Under Universal Serial
Bus controllers, you should see Lattice USB ISP Programmer. If you do not see this, look for the Unknown Device
with the yellow flag. Double click on the Unknown Device icon.
