I don't think it is a good idea that adding usb version as parameters.
If we want to support usb3.0 tablet, we have to change usb_hid_initfn() too
in the future and the usb-mouse, usb-kbd also need to changed despite
usb-mouse and usb-kbd don't support it yet.

Best regards,

Adding a usb3 parameter should the need arise in the future (unlikely
IMO as xhci can handle all three usb speeds) isn't much of a problem I
think.

Error handling should be improved though:

This way it'll be possible to pass NULL for usb2 and have usb_hid_initfn
handle it correctly.

usb_hid_initfn(ev, HID_MOUSE, &desc_mouse, NULL, errp);

patch looks good, the only thing missing is the compat property, to make
sure qemu machine types for 2.1 & older continue to have usb1 mouse+kbd
by default.

The property for the tablet is in hw/i386/pc_piix.c, have a look there
how to do it.  The compat properties for more recent machine types live
in a header file (include/hw/i386/pc.h) so they can be shared between pc
and q35.

Oh, and the patch history should not be in the commit message.  You can
add the history as notes (see 'git notes').  'git format-patch' will use
three dashes to separate the notes and 'git am' will strip them off so
they appear on the list message but not in the commit log.  Adding the
tree dashes separator to the commit message will work too, at least as
long as you don't send pull requests (in which case 'git am' would have
no chance to strip off the notes).

cheers,
  Gerd

I gave mouse and kbd the same treatment as tablet has in
hw/i386/pc_piix.c.
Speaking about properties do I need to add something for display and
head properties?
tablet adds both of them and they seem to be used together, however
keyboard only had display, and I added neither for mouse.

OK I'll move these out of commit messages.
