There are two possible explanations for this error message:

▌Reason 1: The key was removed while Clarity was running.

Solution:

a) Click on the Retry button to reestablish the communication between Clarity and the key.

b) Unplug the key and plug it in again. Click on the Retry button to reestablish the communication.

▌Reason 2: The USB port in which the key is plugged in entered the sleep mode.

Solution:

Go to Start - Control Panel - Hardware and Sound - Device Manager , locate Universal Serial Bus Controller. On each USB Root Hub item right-click and choose Properties. Click on the Power Management tab and uncheck the box for "Allow the computer to turn off this device to save power".

Caution:

Another way to forbid USB ports from entering the sleep mode is in BIOS. This option is however recommended only for advanced users and is usually performed by the local System Administrator.
