Hi Dallas Anderson1,
Thank you for reaching Microsoft Community.
Based on your description, we understand that you have a Surface Pro 9 connected to Surface Dock 1 or 2 then connecting the USB-receiver of your Logitech mouse and keyboard to the dock and it causes the Surface to lag or freeze.
Kindly try these steps below and see if the issue persists:
Connect the dock to the Surface with the USB-receiver connected
Open Device Manager
Expand Universal Serial Bus Controllers
Double-click on all the drivers listed under
Check if Power Management tab is available on each drivers
If yes, go to the Power Management tab then uncheck the box for the "Allow the computer to turn off this device to save power" option
Click OK
Kind regards,
Marrion
