Yes I always upload branches before sending them. This one is
u-boot-dm/usb-working. I should get better at including the branch
name in the cover letter.

I still need to write a test for having two device types which switch
order. Now that I have a USB keyboard emulation I should be able to do
that. I'll then see the impact on 'usb tree'. So you may want to
review the test code only for now.
