+ USB is a host/device protocol, organized with one host (such as a
+ PC) controlling up to 127 peripheral devices.
The USB hardware is asymmetric, which makes it easier to set up:
you can't connect a "to-the-host" connector to a peripheral.

requests back to a USB "gadget driver" in the same host. The host
