Public bug reported:
The mouse is MX Anywhere 2, the keyboard is K750.
If the system is booted with the Logitech Unifying Receiver plugged in,
the keyboard and mouse will keep losing connection. This is most visible
after a short inactivity, i.e. I start typing and nothing appears on
screen for a couple of seconds, or I start moving the mouse and the
cursor takes a couple of seconds to start moving. This also happens
while I'm using the input device, as I was typing this paragraph the
keyboard cut out twice for a second or two.
Additionally, every second time the mouse reconnects, scrolling via the
scroll wheel is painfully slow.
When this is going on, dmesg gets once in some seconds:
[ 381.185787] logitech-hidpp-device 0003:046D:404A.000A: multiplier = 8
[ 507.351776] logitech-hidpp-device 0003:046D:404A.000A: multiplier = 8
[ 540.005778] logitech-hidpp-device 0003:046D:404A.000A: multiplier = 8
[ 627.051731] logitech-hidpp-device 0003:046D:404A.000A: multiplier = 8
[ 769.329768] logitech-hidpp-device 0003:046D:404A.000A: multiplier = 8
I guess it happens when the mouse reconnects.
This can be fixed by unplugging and replugging the Unifying Receiver.
This fixes the problem until next boot.
I tried a couple of older kernel versions and the same thing happened. I
also just tried Fedora 32 beta and it didn't happen there.
