- reduced memory requirements a lot (from >100kb/controller to

560bytes/controller)
- no need for the client of libpayload to implement
  usbdisk_{create,remove}, just because USB was compiled in.
- usb hub support compiles, and works for some trivial cases (no device
  detach, trivial power management)
- usb keyboard support works in qemu, though there are reports that it
  doesn't work on real hardware yet.
- usb keyboard is integrated in both libc-getchar() and curses, if
  CONFIG_USB_HID is enabled
