Disconnecting the mouse triggers unrecoverable error loop

When I use a KVM to switch mouse and keyboard between computers (one Linux, one OpenBSD) -

OpenBSD goes into an un recoverable error loop "uhub2: device problem, disabling port 3"

(This also happens if I have a mouse and keyboard directly plugged into the OpenBSD pc and unplug them.)

Is there a way to tell OpenBSD to ignore the disconnect, please?

BTW1: I'm still running 7.5 for the moment.

BTW2: I did try various Searches for an answer.

BTW3: Dell OptiPlex 7050 (doesn't happen with Linux on any hardware)

Thanks.
