I'm quite sure that if you configure a USB mouse in QEMU, and then
include this driver that you suggest, you should have a virtual USB

Similarly, you could configure a (virtual) PS/2 mouse on the qemu
command line, and include IntelFrameworkModulePkg/Bus/Isa/Ps2MouseDxe.
Then you should have a virtual PS/2 mouse under OVMF.

I just can't see what I'd use either for. I grepped edk2 for
"gEfiSimplePointerProtocolGuid". Thus far the only user for the mouse
seems to be the UEFI Shell's text & hex editors.

... In fact I just built OVMF with this patch, and tested the mouse in
the "hexedit" utility (invoked from the UEFI shell):

 INF  MdeModulePkg/Universal/SmbiosDxe/SmbiosDxe.inf

The virtual PS/2 mouse works just great. If people want it I can submit
a patch for all three flavors, and add the USB mouse driver too.
