U3419W, MacBook, KVM, jerky latent mouse, SOLVED

This isn't a post with a problem, it's a post with a solution. Just in case someone has a similar problem.

I have my U3419W monitor acting as a KVM for a Mac Mini running Debian Linux and a MacBook Pro laptop.  Both computers are connected using the HDMI and USB 3.0 cables and a wireless mouse and keyboard each with their own USB connection fobs.

The Debian Mac Mini runs flawlessly with the U3419W KVM.

The MacBook Pro, however, developed a very stuttery mouse and latent keyboard activity. I tried lots of things moving to the Thunderbolt DisplayPort (caused wireless network dropping issues). Rebooting would help for about 5 minutes. Any heavy activity on the MacBook Pro and the mouse would come to a standstill.

I finally found a reference to the issue in the U3415W User's Guide that indicated that there could be contention or interference issues with devices connected to the USB ports on the back of the monitor and recommended that the connections be moved "away". I plugged in a USB hub with a 2ft wire and move the keyboard and mouse to the hub and it's worked flawless for both computers since then.
