Bizarre keyboard/mouse problem

[ut_helix]

I recently got a new work laptop, and my Logitech wireless keyboard and mouse lag terribly on it, sometimes not registering input, sometimes delaying input, and sometimes registering 10 keypresses all at once.  It uses the Unifying receiver through a USB-C hub that is connected to a USB input switch so I can quickly switch between the laptop and desktop.  This setup worked flawlessly with the same hub on my hold laptop and on my personal desktop.  Here's where it gets strange, when I plug the receiver directly into the USB-A port on the laptop, the problems seem to go away.  I replaced the USB-C hub, same problem.  I've tried removing the USB input switch to no effect (plus this never happens on the desktop going through the switch), it seems 100% related to the USB-C port on my laptop.  Laptop is running Windows 10.  Has anyone seen something like this before?

What model keyboard/mouse is it?

If it's the K270 bundle, that's literally just the way it is. Can be mitigated by putting the receiver in the highest USB throughput port on the mobo. I straight up could not get it to work on 2.0, and at USB 3 10gbps (whatever it's called this week) it would work reliably maybe 70% of the time. Twisting, pressure, and hitting it would occasionally get it to work better.
