samux 8:93da8ea2708b 34 * - a message is queued in queue_usb_event with the id DEVICE_CONNECTED_EVENT

samux 8:93da8ea2708b 37 * - reads the device descriptor
samux 8:93da8ea2708b 38 * - sets the address of the device
samux 8:93da8ea2708b 39 * - if it is a hub, enumerates it
samux 8:93da8ea2708b 40 * - device disconnected:
samux 8:93da8ea2708b 41 * - a message is queued in queue_usb_event with the id DEVICE_DISCONNECTED_EVENT
samux 8:93da8ea2708b 42 * - when the usb_thread receives the event, it:
samux 8:93da8ea2708b 43 * - free the device and all its children (hub)
