My Operating System is is Ubuntu 18.04 and my machine does not have a built in Bluetooth device. I have a Logitech mouse and its usb-dongle, both work fine.
I can see the mouse as a paired device at Solaar application and it says "Up to 6 devices can be paired to this receiver".
My problem is that I can not pair my Logitech Keyboard K730. I have the following information from my machine
hciconfig scan Can't get device info: No such device hcitool dev Devices:
So, the Logitech dongle is not recognized as a device. My main question is if I can pair Logitech K760 to logitech unifying receiver as second device or not?
