Logitech Usb Unifying Receiver Driver Download 'LINK'

It may be that your unifying receiver is just a little too far from the mouse or trackball. I encountered this in cases where I plugged the unifying receiver into the desktop,(about 4 feet from the mouse, not in line of sight) and it only worked sporadically until I plugged it into a usb bridge that was only two feet away from my mouse. This was on fedora 29 and 30. Fedora 30 seems to be more sensitive than fedora 29.
But i'm using the unifying receiver and not the bluetooth function because my device does not recognize BT Mouse / Keyboard for the UEFI Setup. So i decided to switch from Bluetooth to Unifying Receiver that had been deliverd with the input devices (MX Vertical and Craft Keyboard)
I agree, if you have a Logitech wireless mouse of any kind, you need to use the unifying receiver that it should have came with, if not, you'll have to purchase a Logitech unifying receiver unit, but they are cheap, so not a big deal.
Once plugged in though, you will need to go to the software center, search for, and install the Logitech unifying receiver driver. Once that is done, restart the computer, and it should be able to detect and use the mouse, if it hasn't done so already.
The issue was that my receiver died. Luckily I had an extra so I used logitech's Connect-your-device-to-a-Logitech-USB-receiver to attach the new receiver to my mouse. Once I did that I was able to connect the mouse to my computer.
