After Sonoma 14.4 update USB hub not working on MacBook

I have my MacBook (MacBook Pro 16 M2 Pro) connected to my monitor (Gigabyte M34WQ 34 Inch IPS Ultrawide WQHD (3440 x 1440)) via a thunderbolt 3 cable.

I have my keyboard and mouse connected to the USB ports in my monitor.


After updating, my keyboard and mouse are no longer being detected on my MacBook.

Before updating, it was working fine.


I can't find anything online about this issue


Can anyone help?


thanks

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:


  1. System Settings->Privacy&Security->Allow accessories to connect->Ask every time
  2. Turn off monitor (at the wall is best) and disconnect it
  3. Reboot
  4. 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.
