Hi Ed,

Whilst we wait for the graphics I sent with my USB
controller options to be approved by the moderator,
where did you find that option?  I only have USB2,
USB3, Hypervisor default (USB2).

USB options may depend on previous choices.  For example, different 
"machine types" have different capabilities.   

https://github.com/qemu/qemu/blob/master/docs/usb2.txt menitions
differences for XHCI, EHCI, and UHCI.   XHCI does USB's1, 2, &3.
