I downloaded an installed the Sena Device Manager and updated the firmware on one of the two Sena 10S in my dual pack. I cannot get the second 10S device to be recognized by the Device Manager. I have closed and re-opened the program. rebooted the PC. It's not the USB cable because both USB cables work with the first 10S unit. I can repeatedly connect the one 10S unit and it is consistently recognized but the second unit fails to be recognized.
Is there something wrong with the second unit?
thank-you in advance for any help
