2 * This file holds USB constants and structures that are needed for
3 * USB device APIs. These are used by the USB device model, which is
4 * defined in chapter 9 of the USB 2.0 specification and in the
5 * Wireless USB 1.0 (spread around). Linux has several APIs in C that
6 * need these:
7 *
8 * - the master/host side Linux-USB kernel driver API;
9 * - the "usbfs" user space API; and
10 * - the Linux "gadget" slave/device/peripheral side driver API.
11 *
12 * USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems
13 * act either as a USB master/host or as a USB slave/device. That means
14 * the master and slave side APIs benefit from working well together.
15 *
16 * There's also "Wireless USB", using low power short range radios for
17 * peripheral interconnection but otherwise building on the USB framework.
18 *
19 * Note all descriptors are declared '__attribute__((packed))' so that:
20 *
21 * [a] they never get padded, either internally (USB spec writers
22 * probably handled that) or externally;
23 *
24 * [b] so that accessing bigger-than-a-bytes fields will never
25 * generate bus errors on any platform, even when the location of
26 * its descriptor inside a bundle isn't "naturally aligned", and
27 *
28 * [c] for consistency, removing all doubt even when it appears to
29 * someone that the two other points are non-issues for that
30 * particular descriptor type.
