M1, USB and 11.3

[stw]

11.3 makes using my Apple USB keyboard unusable. A few minutes not using it (using bluetooth trackbad or mouse only) and it does not react until it get unplugged.

UPS software does not find the USB-connected UPs any more since 11.3.

Are you using a hub? I've noticed similar behavior before 11.3 when connecting to some USB hubs mixed with 2.0 and 3.0 devices.

Yes. There is no alternative. I have 8-10 devices connected via USB.
My monitor has a KVM switch. This is my prreferred connection for the keyboard.
