I was issued this laptop for working from home. I bought a KVM switch so that I could use it with my existing PC peripherals. My company also sent me a Dell Universal Dock D6000. When I attempt to use either of these devices to run both my mouse and keyboard through a single USB port, I find that the mouse and keyboard constantly disconnect and reconnect, either fully, or by not taking inputs for a couple seconds at a time, but remaining powered. The issue is worse when I am running the software that manages the mouse and keyboard. The issue also occurs on the Latitude 3520 I have. I'm worried this may be an issue with the speed of the USB ports. Has anyone experienced a similar issue?

Sorry to hear that. To me this sounds like youre experiencing some usb hub/bus kind of bandwith / power failure behavior.
Are all of your drivers including the bios updates up to date?

Dell, Inc. - Firmware - 0.1.22.0 is the one I installed. Notably, I do still experience a more minor version of the issue intermittently. It's solvable now by reseating my main USB cable though, and the symptoms aren't quite so impactful when it is going on. I think the USB ports on this laptop are just kind of slow
