To understand all the Linux-USB framework, you'll use these resources:

    * This source code.  This is necessarily an evolving work, and
      includes kerneldoc that should help you get a current overview.
      ("make pdfdocs", and then look at "usb.pdf" for host side and
      "gadget.pdf" for peripheral side.)  Also, Documentation/usb has
      more information.

    * The USB 2.0 specification (from www.usb.org), with supplements
      such as those for USB OTG and the various device classes.
      The USB specification has a good overview chapter, and USB
      peripherals conform to the widely known "Chapter 9".

    * Chip specifications for USB controllers.  Examples include
      host controllers (on PCs, servers, and more); peripheral
      controllers (in devices with Linux firmware, like printers or
      cell phones); and hard-wired peripherals like Ethernet adapters.

    * Specifications for other protocols implemented by USB peripheral
      functions.  Some are vendor-specific; others are vendor-neutral
      but just standardized outside of the www.usb.org team.

Here is a list of what each subdirectory here is, and what is contained in
them.

core/           - This is for the core USB host code, including the
                  usbfs files and the hub class driver ("khubd").

host/           - This is for USB host controller drivers.  This
                  includes UHCI, OHCI, EHCI, and others that might
                  be used with more specialized "embedded" systems.

gadget/         - This is for USB peripheral controller drivers and
                  the various gadget drivers which talk to them.


Individual USB driver directories.  A new driver should be added to the
first subdirectory in the list below that it fits into.

image/          - This is for still image drivers, like scanners or
                  digital cameras.
../input/       - This is for any driver that uses the input subsystem,
                  like keyboard, mice, touchscreens, tablets, etc.
../media/       - This is for multimedia drivers, like video cameras,
                  radios, and any other drivers that talk to the v4l
                  subsystem.
../net/         - This is for network drivers.
serial/         - This is for USB to serial drivers.
storage/        - This is for USB mass-storage drivers.
class/          - This is for all USB device drivers that do not fit
                  into any of the above categories, and work for a range
                  of USB Class specified devices. 
misc/           - This is for all USB device drivers that do not fit
                  into any of the above categories.
