123cd1385SRemy Bohmer /* 223cd1385SRemy Bohmer * This file holds USB constants and structures that are needed for 323cd1385SRemy Bohmer * USB device APIs. These are used by the USB device model, which is 423cd1385SRemy Bohmer * defined in chapter 9 of the USB 2.0 specification and in the 523cd1385SRemy Bohmer * Wireless USB 1.0 (spread around). Linux has several APIs in C that 623cd1385SRemy Bohmer * need these: 723cd1385SRemy Bohmer * 823cd1385SRemy Bohmer * - the master/host side Linux-USB kernel driver API; 923cd1385SRemy Bohmer * - the "usbfs" user space API; and 1023cd1385SRemy Bohmer * - the Linux "gadget" slave/device/peripheral side driver API. 1123cd1385SRemy Bohmer * 1223cd1385SRemy Bohmer * USB 2.0 adds an additional "On The Go" (OTG) mode, which lets systems 1323cd1385SRemy Bohmer * act either as a USB master/host or as a USB slave/device. That means 1423cd1385SRemy Bohmer * the master and slave side APIs benefit from working well together. 1523cd1385SRemy Bohmer * 1623cd1385SRemy Bohmer * There's also "Wireless USB", using low power short range radios for 1723cd1385SRemy Bohmer * peripheral interconnection but otherwise building on the USB framework. 1823cd1385SRemy Bohmer * 1923cd1385SRemy Bohmer * Note all descriptors are declared '__attribute__((packed))' so that: 2023cd1385SRemy Bohmer * 2123cd1385SRemy Bohmer * [a] they never get padded, either internally (USB spec writers 2223cd1385SRemy Bohmer * probably handled that) or externally; 2323cd1385SRemy Bohmer * 2423cd1385SRemy Bohmer * [b] so that accessing bigger-than-a-bytes fields will never 2523cd1385SRemy Bohmer * generate bus errors on any platform, even when the location of 2623cd1385SRemy Bohmer * its descriptor inside a bundle isn't "naturally aligned", and 2723cd1385SRemy Bohmer * 2823cd1385SRemy Bohmer * [c] for consistency, removing all doubt even when it appears to 2923cd1385SRemy Bohmer * someone that the two other points are non-issues for that 3023cd1385SRemy Bohmer * particular descriptor type. 3123cd1385SRemy Bohmer */
