4KSW41-KVM-Pro keyboard stops working when switching input

I have a 4KSW41-KVM-Pro that is connected to a MacBook Pro and a Lenovo Windows Laptop. I am using a Logitech mouse and an Apple A1243 USB keyboard.

Everything works OK with the MacBook, but the keyboard stops working on the Windows machine when I switch away and back to it. The mouse continues to work - it is just the keyboard that is a problem. I have tried a different Apple USB keyboard and an old USB one from a Windows desktop, but they also have the same problem.

The keyboard starts working again if I unplug the USB lead between the KVM and the Windows machine and plug it back in again.

This obviously makes the 4KSW41-KVM-Pro completely useless as a KVM. Is there a firmware update available that fixes this?

Edited to add - I have tried using different USB ports on the machine.

Looks like the switching works ok if I don’t use hotkeys (which is a feature I use a lot).

Sounds the same as the issue reported here for the iDock D23.

Support have said that it is not possible to update the firmware for the 4KSW41-KVM-Pro, so I will have to return the item.
