There can be a few instances where:
Power Button - Ensure that the Power button is turned on.
This is indicated by a green light at the back of the GemCam once the USB cable is connected.
Relaunch the GemLightbox Application - If the GemCam remains unconnected, please attempt a restart of the GemLightbox Application.
Reinstall the GemHub - This will delete any existing cache and the application will be treated like a new install again. Data will not be lost as it is stored on cloud.
Restart Computer - Sometimes connection issues can be solved by just restarting the computer.
Compatibility with Desktop - The GemCam may appear to be lagging due to performances issues with your computer.
We recommend operating the GemCam on desktops that meet the recommended system requirements.
