#vi xxx/.../qca/src/linux-3.14/drivers/usb/README
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.
