Sena20S Evo - problem with USB in Device Manager

Hi, I have a problem to connect Sena 20SEvo via USB. There is no Device recognition in Device Manager. Like win 10 doesn't see Sena Device - there is no on the devices list. 

I reinstal several times Sena Bluetooth Device Manager (on admin permitions) but it does't help. 

I'm not able to update frimware in my device. Is there any solution to my win recognized Sena device? 

Regards Mariusz
