Add support for UC-Logic WP4030U, WP5540U and WP8060U tablets.
These tablets are usually sold by Genius, Trust and possibly others under
different names and in different cases, but with the original USB
vendor/product IDs.
Currently, these tablets are supported by standalone X.org driver WizardPen.
This patch aims to fix them in the kernel and make them supported by the
generic evdev X.org driver. Still, some minor fixes in the X.org driver are
to be made for the full stack support.

Module roccat is a char device used to report special events of roccat hardware
to userland. These events include requests for on-screen-display of profile or
dpi settings or requests for execution of macro sequences that are not stored
in device. The information in these events depends on hid device implementation
and contains data that is not available in a single hid event or else hidraw
could have been used.
It is inspired by hidraw, but uses only one circular buffer for all readers.

The whole point of making some of the drivers automatically selected
unless 'EMBEDDED' was to handle quirks transparently after their separation
from the generic core.
Over time, some of the later-added quirks grew into more standalone drivers,
implementing non-trivial features a being larger than a few bytes of code.
In addition to that, some of the standalone drivers don't make sense for
99.9% of the users, as they are very specific to rare devices.
Therefore build by default in only those drivers which
- we historically used to support even before quirk separation from the
core code
- are isolated enough and likely to hit quite large portion of the
users anyway (Microsoft, Logitech)

This Patch adds support for Kone gaming mouse from Roccat.
It provides access to profiles, settings, firmware, weight,
actual settings etc. through sysfs attributes.
Event handling of this mouse differs from standard hid behaviour
in that tilt button press is reported in each move event which
results in strange behaviour if not handled by the driver.
This is a heavily reworked version of the previously introduced driver.
The changes include most of the previously raised concerns,
memory leak and other fixes, code cleanups, adoption of additional
achieved knowlege about the hardware and is (IMHO) a much better version
than before even when I exchanged reduced USB-IO with a bigger memory
consumption.
I refused to implement one mentioned point:
Removing the 'just-because-we-can' attributes. Motivation:
Reading the clipped in weight: I'm no gamer and can't determine the
usefulness of this feature but if the manufacturer implements such a
feature it might make sense to someone and I would unwillingly limit the
functionality besides its such a small feature.
Reading the actual profile and dpi settings: Here I can testify that one
can get lost of the actual settings when switching back and forth.
The manufacturers windows driver has the ability for on-screen-display
of the values and there is a mouse in the market that has an lcd on the
underside of it to show these values. So I think this feature makes sense
not only for me and shouldn't be removed.

The Magic Mouse requires that a driver send an unlock Report(Feature) command,
similar to the Wacom wireless tablet and Sixaxis controller quirks. This turns
on an Input Report that isn't published in the input Report descriptor that
contains touch data (and usually overrides the normal motion and click Report).
Because the mouse has only one switch and no scroll wheel, the driver
(under control of parameters) emulates a middle button and scroll wheel.
User space could also ignore and/or re-synthesize those events based on
the reported events.

associated with the host's HIDP stack) are at

For historical reasons, we don't have most of the in-tree
drivers residing on hid-bus properly selectable in kernel
configuration unless CONFIG_EMBEDDED is set.
This has been introduced on Linus' request from 14 Oct
===
As to the Kconfig options - do they really add so much space that you need to
ask for the quirks? You didn't use to. Can you make the questions depend on
EMBEDDED, or at least on the HID_COMPAT thing or whatever?
===
This still makes perfect sense for small and tiny drivers, which
just fix report descriptors, fix up HID->input mappings that slightly
violates HUT standard, send one extra packet to the device that is
needed before it becomes functional, etc.
Since then, we have been gathering more and more HID-bus drivers,
which are full-fledged drivers. For these, the size argument becomes
more valid. Plus the devices are much more special than "just violates
HID specification in this one or two tiny unimportant points".
Therefore I am marking such drivers as properly selectable no matter
the setting of CONFIG_EMBEDDED, while keeping all the small and tiny
ones compiled by default.

It is a little bit inconvenient for people who have some non-standard
HID hardware (usually violating the HID specification) to have to
recompile kernel with CONFIG_HID_DEBUG to be able to see kernel's perspective
of the HID report descriptor and observe the parsed events. Plus the messages
are then mixed up inconveniently with the rest of the dmesg stuff.
This patch implements /sys/kernel/debug/hid/<device>/rdesc file, which
represents the kernel's view of report descriptor (both the raw report
descriptor data and parsed contents).
With all the device-specific debug data being available through debugfs, there
is no need for keeping CONFIG_HID_DEBUG, as the 'debug' parameter to the
hid module will now only output only driver-specific debugging options, which has
absolutely minimal memory footprint, just a few error messages and one global
flag (hid_debug).
We use the current set of output formatting functions. The ones that need to be
used both for one-shot rdesc seq_file and also for continuous flow of data
(individual reports, as being sent by the device) distinguish according to the
passed seq_file parameter, and if it is NULL, it still output to kernel ringbuffer,
otherwise the corresponding seq_file is used for output.
The format of the output is preserved.

Currently, the hid-*ff force feedback drivers, which claim the blacklisted

However we want the device to be supported even when the kernel is configured

This patch fixes the drivers in a way that they get compiled even if force
feedback is turned off; all the force feedback support code is compiled out in
such case, and the driver works as a usual driver on HID bus, claiming and

hidraw is an interface that is going to obsolete hiddev one
day.
Many userland applications are using libusb instead of using
kernel-provided hiddev interface. This is caused by various
reasons - the HID parser in kernel doesn't handle all the
HID hardware on the planet properly, some devices might require
its own specific quirks/drivers, etc.
hiddev interface tries to do its best to parse all the received
reports properly, and presents only parsed usages into userspace.
This is however often not enough, and that's the reason why
many userland applications just don't use hiddev at all, and
rather use libusb to read raw USB events and process them on
their own.
Another drawback of hiddev is that it is USB-specific.
hidraw interface provides userspace readers with really raw HID
reports, no matter what the low-level transport layer is (USB/BT),
and gives the userland applications all the freedom to process
the HID reports in a way they wish to.
