mbed_official 0:a554658735bf 32 * How interrupts are processed:
mbed_official 0:a554658735bf 33 * - new device connected:
samux 8:93da8ea2708b 34 * - a message is queued in queue_usb_event with the id DEVICE_CONNECTED_EVENT
samux 8:93da8ea2708b 35 * - when the usb_thread receives the event, it:
samux 8:93da8ea2708b 36 * - resets the device
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)
samux 8:93da8ea2708b 44 * - td processed
samux 8:93da8ea2708b 45 * - a message is queued in queue_usb_event with the id TD_PROCESSED_EVENT
samux 8:93da8ea2708b 46 * - when the usb_thread receives the event, it:
samux 8:93da8ea2708b 47 * - call the callback attached to the endpoint where the td is attached
