We havn't added shortcuts like this to qemu for a while. There are a
bunch of other new things which don't have a shorthand command line
switch too. I suspect -usb2 wouldn't be very welcome @ qemu-devel. You
can try sending a patch though, shouldn't be hard, code is there as q35
uses it.
There is also the option to stick things into a config file (see
docs/q35-chipset.cfg for an example), then do "-readconfig usb2.cfg".

Thats why the "if the guest is new enough" above. With windows this
works nicely only with win8+ (ships with xhci drivers). For older
windows versions it is not really an option, you'd have to hunt down
drivers on the internet etc.
