Everywhere that I have read online has said that as long as the devices are paired to the adapter first on a windows machine using the unifying software that it would work fine, so I have done that, and it works fine on windows.

However on Ubuntu nothing is making the adapter work.

Plugging in the adapter gives this output in dmesg:

[ 2435.192014] usb 3-2: >new full-speed USB device number 10 using xhci_hcd
[ 2435.210390] usb 3-2: >New USB device found, idVendor=046d, idProduct=c52b

[ 2435.216598] logitech-djreceiver: probe of 0003:046D:C52B.001F failed with error -32

I tried following this guide and in the end ran sudo /opt/unify/pairing_tool /dev/hidraw0 but the output is:

Unable to open device: No such file or directory

Ok, so I have found a "fix" basically, re plugging the adapter into a different usb port (doesn't always work, so I have to loop between my ports, sometimes ending up with it working on the original port!).

On the times when it fails it displays that same -32 error message in dmesg
