T480 Will not boot with a USB Mouse or Keyboard plugged in, Laptop or Dock

When we have a USB Mouse and or Keyboard plugged into the laptop or the ThinkPad Pro Dock (M3F00) it will not boot, it will boot however if we turn off the USB UEFI Bios Support off, then we will have to use the laptop keyboard to logged in. Then the external mouse and keyboard will start working after that.

How do we get this to work with the external keyboard and mouse. Seems to be a hit and miss issue with our organization.

Added note...Mcafee Endpoint Encryption is also installed, and the system will lock up either before or at the McAfee login screen.
