Details:

Situation:  GRUB freezes on my laptop at countdown 10 with not ability to move
anything.  Currently, this happens every time my external keyboard is
attached.

Equipment:  HP X360 i7 configured dual boot.  USB 3.1 (USB-A), USB 3.1 (USB-C)
and Thunderbolt (USB-C).  UEFI Boot.

This is an issue because I want to leave my computer docked and survive a
reboot without having to unplug the keyboard all the time.  I've googled
solutions and "legacy boot" would disable my installed OSs.  There is not bios
option for "legacy USB" support and none of the GRUB-2 configurations to
enable USB, usb-keyboard, etc... have worked.

MY KEYBOARD works before and after grub.... meaning, that at power-on, I can
press F10 on usb-keyboard and get to BIOS.  Plugging in the keyboard after
GRUB boot, keyboard works.

I have tried three separate keyboard... all of which I know are working.
