Having problems with your devices, monitors, keyboards, mice, using a hub after updating to Apple Sonoma 14.4?
Someone in the Apple Support Community has mentioned that this has helped him, though no one is sure if it will be a permanent fix, but give it a try;
I had the same issue with an LG monitor connected by USB3 -- the mouse plugged into the USB hub on the monitor didn't work after the 14.4 upgrade.
Rebooting, reconnecting wires, etc, didn't help.
However, this worked:
- System Settings->Privacy&Security->Allow accessories to connect->Ask every time
- Turn off monitor (at the wall is best) and disconnect it
- Reboot
- Reconnect the monitor then turn it on.
At this point I got a popup asking if I agreed to the assessory and I answered yes. Since then the mouse works fine. Hopefully it will stay that way.
