Yes it seems like they’re set on a proven design. I used to use a USB hub and have the two cables next to one another on my desk, manually unplugging replugging it to transfer keyboard and mouse at once. With USB extenders so both machines have their plus right next to another. But I saw in this thread there are USB switchers so maybe that’s a solution?
