Pretty much every single USB device ever created fails some part or another of the USB spec. Because the spec is enormous, truly giant, and ambiguous in parts.

I guess using a hub for a keyboard is a little more niche.

  Heh funny I have a laptop connected to the USB hub in a relatively recent Fujitsu screen and then an old USB 2.0 hub connected to that one with keyboard and mouse connected to it. Works flawlessly. Guess I got lucky.

  I would have assumed that connecting your PC to a hub built-in to your monitor then connecting keyboard and mice into the monitor would be a somewhat common configuration

    I would guess hubs built into monitors to be tested with this exact use-case.

    I don't know; I tried this once (on a Dell U2715H), and the input from both the mouse and the keyboard got very jittery, to the point of making the computer very difficult to operate. I suppose there was some interference from processing and displaying HDMI signal; whatever it was, I decided not to bother with built-in display USB hubs.

  Most of my computing life the last decade is living off a laptop hooked up to a dock and a dinky little 4port usb2.0 hub plugged into that dock for webcam, mouse, keyboard, midi controller. It's pretty nice to just one cable my laptop into a desktop.

Huh. I use a hub as a cheap KVM equivalent, and noticed that every now and again the keyboard just fails to work until replugged. Guess this is a bit more widespread, but you'd thought they'd test with keyboards.
