Disconnecting the mouse triggers unrecoverable error loop

[David Colburn]

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.
