Windows 10 Driver Installation Help

A recent Windows 10 update forces driver signing which prevents Windows 10 assigning the COMET USB driver. This is signified by a yellow exclamtion mark in device manager against COMET USB.

To enable Windows 10 to install the driver, you need to disable device driver signing by following the instructions below.
