Dynamixel Wizard does not recognize device in Ubuntu

I have the Dynamixel Robot Actuator servos.
Then i got the Dynamixel Wizard 2.0 software.

The servos are not recognized under Ubuntu Linux 20.0.
The scan results all output “Connection Failed”. Keep in mind that the port exists - it can see the port called “ttyUSB0 (USB - Serial Converter)”.
However, the software in Windows can see the servos.

I have to make them work under Linux. Does anyone know why i cannot make the software see them?

Have you added your user to the dialout group necessary for USB port access? Without that, you will not have the correct permissions in order to open the serial connection over the USB port.
