Elements EPP doesn’t scan USB drive when “Action when USB storage device is plugged in” is set to scan USB

Issue:

Elements Endpoint Protection doesn't scan a USB drive when "Action when USB storage device is plugged in" is set to:

• "scan USB and show results to user" 
• "Silently scan USB" 
• "Force scan USB and show result to user" 
• "Ask user to scan USB" 

Resolution:

Make sure that the USB drive that you have connected to the computer is a USB thumb drive or an SD card. If it is an external HDD, it will not be scanned even if it would use a USB connection.

This is expected behavior since the "Action when USB storage device is plugged in" feature uses internal Windows device flags which tells Windows which type of device is connected. It's not using device ID or hardware ID.
