What occurred to me right after sending the previous reply - I think
it was said earlier that it doesn't matter which port the keyboard was
plugged in. Does that hold if it gets plugged into a port connected to
the other EHCI HC? I.e. does the failure then occur during the other
driver initialization instance?
