* MacBook Pro 2017
* DELL U2717D Display
* Logitech unifying receiver and mouse m705
Mouse & receiver work have worked for a year. I upgraded to Mojave 2 weeks ago, and it has been working fine for the last two weeks.
Beginning today 10/7/18, mouse no longer works when the receiver is plugged into any port on monitor.
Mouse works when receiver is plugged into Mac with USB C adapter.
I checked USB ports on the monitor and they still work with other USB devices.
I checked with two different Logitech receivers and mice and neither worked.
I reinstalled the Logitech software and restarted.
Still doesn't work.
I'm stumped. Does anyone else have any ideas?
