What is the meaning of the green light at the software dongle?

When the light is on. your dongle is installed properly and ready to use. When the light is blinking, the dongle driver was not installed correctly. Remove the dongle and plug it in again after several seconds, preferably to another USB port.

Please note that in case of Windows operating system it can take some time until the proper software driver is found and installed by your system. Please wait until “New hardware is ready to use” notice is displayed. If the notice was displayed and the dongle light is still blinking, your dongle was not properly recognised by the system.

The dongle is completely driverless, it uses built-in driver of the operating system No external driver is neccessary to make the dongle working under Windows. Under Linux, the standard usbhid driver has to be installed. It is the standard part of the most Linux distributions. If it is not included with your system, please install usbhid driver manualy before attaching the dongle.
