Logitech devices use a vendor protocol to communicate various
information with the device. This protocol is called HID++,
and an exerpt can be found here:
https://drive.google.com/folderview?id=0BxbRzx7vEV7eWmgwazJ3NUFfQ28&usp=shar
The main difficulty which is related to this protocol is that
it is a synchronous protocol using the input reports.
So when we want to get some information from the device, we need
to wait for a matching input report.
This driver introduce this capabilities to be able to support
the multitouch mode of the Logitech Wireless Touchpad T651
(the bluetooth one). The multitouch data is available directly
from the mouse input reports, and we just need to query the device
on connect about its caracteristics.
HID++ and the touchpad features has a specific reporting mode
which uses pure HID++ reports, but Logitech told us not to use
it for this specific device. During QA, they detected that
some bluetooth input reports where lost, and so the only supported
mode is the pointer mode.

ISDv4 and v5 are plain HID devices. We can directly implement a generic
HID parsing/handling and remove the need to manually add those PID in
the list of supported devices.
This patch implements the pen support only. The finger part will come in
a later patch.
To be properly notified of an .event() and a .report(), we need to force
hid-core to go through the HID parsing. By default, wacom.ko binds only
hidraw, so the hid parsing is not done by hid-core. When a true HID device
is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will
force hid-core to parse the incoming reports.
(Note that this can be easily backported by directly setting the .claimed
flag to HID_CLAIMED_DRIVER even if hid-core does not support
HID_CONNECT_DRIVER)

All USB Wacom tablets are actually HID devices.
For historical reasons, they are handled as plain USB devices.
The current code makes more and more reference to the HID subsystem
like implementing its own HID report descriptor parser to handle new
devices.
From the user point of view, we can transparently switch from this state
to a driver handled in the HID subsystem and clean up a lot of USB specific
code in the wacom.ko driver.
The other benefit once the USB dependecies have been removed is that we can
use a tool like uhid to make regression tests and allow further cleanup or
new implementations without risking breaking current behaviors.
To match the current handling of devices in wacom_wac.c, we rely on the
hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when
it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the
device is plain HID. There is thus a one to one matching between the list
of supported devices before and after the switch from USB to HID.

The Microsoft Surface Type/Touch Cover 2 is a fancy device which advertised
itself as a multitouch device but with constant input reports.
This way, hid_scan_report() gives the group MULTITOUCH to it, but
hid-multitouch can not handle it due to the constant collection ignored
by hid-input.
To prevent such crap in the future, and while we do not fix this particular
device, make the scan_report coherent with hid-input.c, and ignore constant
input reports.

This reverts commit 117309c51d.
The MS Surface Pro 2 has an USB composite device with 3 interfaces
- interface 0 - sensor hub
- interface 1 - wacom digitizer
- interface 2 - the keyboard cover, if one is attached
This USB composite device changes it product id dependent on if and which
keyboard cover is attached. Adding the covers to hid_have_special_driver
prevents loading the right hid drivers for the other two interfaces, all 3
get loaded with hid-microsoft. We don't even need hid-microsoft for the
keyboards. We have to revert this to load the right hid modules for each
interface.

Certain devices with class HID, protocol None did not work with the HID
driver at one point, and as a result were bound to usbtouchscreen
instead as of commit 139ebe8 ("Input: usbtouchscreen - fix eGalax HID
ignoring"). This change was prompted by the following report:
https://lkml.org/lkml/2009/1/25/127
Unfortunately, the device mentioned in this report is no longer
available for testing.
We've recently discovered that some devices with class HID, protocol
None do not work with usbtouchscreen, but do work with usbhid. Here is
the report that made this evident:
http://comments.gmane.org/gmane.linux.kernel.input/31710
Driver binding for these devices has flip-flopped a few times, so both
of the above reports were regressions.
This situation would appear to leave us with no easy way to bind every
device to the right driver. However, in my own testing with several
devices I have not found a device with class HID that does not work with
the current HID driver. It is my belief that changes to the HID driver
since the original report have likely fixed the issue(s) that made it
unsuitable at the time, and that we should prefer it over usbtouchscreen
for these devices. In particular, HID quirks affecting these devices
were added/removed in the following commits since then:
fe6065d HID: add multi-input quirk for eGalax Touchcontroller
77933c3 Merge branch 'egalax' into for-linus
ebd11fe HID: Add quirk for eGalax touch controler.
d34c4aa HID: add no-get quirk for eGalax touch controller
This patch makes the HID driver no longer ignore eGalax/D-Wav/EETI
devices with class HID. If there are in fact devices with class HID
that still do not work with the HID driver, we will see another round of
regressions. In that case I propose we investigate why the device is
not working with the HID driver rather than re-introduce regressions for
functioning HID devices by again binding them to usbtouchscreen.
The corresponding change to usbtouchscreen will be made separately.

Revert some changes done in 7746383868.
Revert all changes done in hidinput_calc_abs_res as it mistakingly used
"Unit" item exponent nibbles to affect resolution value. This wasn't
breaking resolution calculation of relevant axes of any existing
devices, though, as they have only one dimension to their units and thus
1 in the corresponding nible.
Revert to reading "Unit Exponent" item value as a signed integer in
hid_parser_global to fix reading specification-complying values. This
fixes resolution calculation of devices complying to the HID standard,
including Huion, KYE, Waltop and UC-Logic graphics tablets which have
their report descriptors fixed by the drivers.
Explanations follow.
There are two "unit exponents" in HID specification and it is important
not to mix them. One is the global "Unit Exponent" item and another is
nibble values in the global "Unit" item. See 6.2.2.7 Global Items.
The "Unit Exponent" value is just a signed integer and is used to scale
the integer resolution unit values, so fractions can be expressed.
The nibbles of "Unit" value are used to select the unit system (nibble
0), and presence of a particular basic unit type in the unit formula and
its *exponent* (or power, nibbles 1-6). And yes, the latter is in two
complement and zero means absence of the unit type.
Taking the representation example of (integer) joules from the
specification:
[mass(grams)][length(centimeters)^2][time(seconds)^-2] * 10^-7
the "Unit Exponent" would be -7 (or 0xF9, if stored as a byte) and the
"Unit" value would be 0xE121, signifying:
Nibble Part Value Meaning
----- ---- ----- -------
0 System 1 SI Linear
1 Length 2 Centimeters^2
2 Mass 1 Grams
3 Time -2 Seconds^-2
To give the resolution in e.g. hundredth of joules the "Unit Exponent"
item value should have been -9.
See also the examples of "Unit" values for some common units in the same
chapter.
However, there is a common misunderstanding about the "Unit Exponent"
value encoding, where it is assumed to be stored the same as nibbles in
"Unit" item. This is most likely due to the specification being a bit
vague and overloading the term "unit exponent". This also was and still
is proliferated by the official "HID Descriptor Tool", which makes this
mistake and stores "Unit Exponent" as such. This format is also
mentioned in books such as "USB Complete" and in Microsoft's hardware
design guides.
As a result many devices currently on the market use this encoding and
so the driver should support them.

The Win 8 detection is sufficiently complex to warrant use of the full

the existing HID parser in hid-core for hid_scan_report() by re-using the
code from hid_open_report(). hid_parser_global, hid_parser_local and
hid_parser_reserved does not have any side effects. We just need to
reimplement the MAIN_ITEM callback to have a proper parsing without side

implement() is setting bytes in LE data stream. In case the data is not
aligned to 64bits, it reads past the allocated buffer. It doesn't really
change any value there (it's properly bitmasked), but in case that this
read past the boundary hits a page boundary, pagefault happens when
accessing 64bits of 'x' in implement(), and kernel oopses.
This happens much more often when numbered reports are in use, as the
initial 8bit skip in the buffer makes the whole process work on values
which are not aligned to 64bits.
This problem dates back to attempts in 2005 and 2006 to make implement()
and extract() as generic as possible, and even back then the problem
was realized by Adam Kroperlin, but falsely assumed to be impossible
to cause any harm:
http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg47690.html
I have made several attempts at fixing it "on the spot" directly in
implement(), but the results were horrible; the special casing for processing
last 64bit chunk and switching to different math makes it unreadable mess.
I therefore took a path to allocate a few bytes more which will never make
it into final report, but are there as a cushion for all the 64bit math
operations happening in implement() and extract().
All callers of hid_output_report() are converted at the same time to allocate
the buffer by newly introduced hid_alloc_report_buf() helper.
Bruno noticed that the whole raw_size test can be dropped as well, as

When device with the DELIMITER tag in its report descriptor is encountered
during parsing, it's mistakenly immediately refused by HID core for no
justifiable reason.

Pull input updates from Dmitry Torokhov:
"First round of updates for the input subsystem.
You will get a new touchsreen driver for Cypress 4th generation
devices, a driver for a special controller implementing PS/2 protocol
in OLPC devices, and a driver for power key for SiRFprimaII PWRC.
HID and bcm5497 now support for the 2013 MacBook Air.
EVIOCGKEY and the rest of evdev ioctls now flush events of matching
type from the client's event queue so that clients can be sure any
events received after issuing EVIOCG* ioctl are new events.
And a host of cleanups and improvements in other drivers"

hdrw->raw event can return three different return value types:
- ret < 0 indicates that the hdrv driver found an error while parsing
- ret == 0 indicates no error has been encountered, and the driver has
processed the report
- ret > 0 indicates that there was no parsing error, and the driver hasn't
processed the event.
Calling hid_report_raw_event() has to be called appropriately so that it
reflects what has been done by ->raw_event() callback, otherwise we might
updates of the in-kernel structure are lost upon arrival of the report, which
is wrong.

This is a driver for ELO 4000/4500 devices which report themselves as
HID devices, but do not really send HID events on touch. So we
introduce a new HID 'quirk' driver with a raw_event handler where we
take care of those events.
What we need additionally is an input_configured hook, because the
device does not mention anything about PRESSURE and TOUCH in its
report descriptor, but it actually generate those. So we set the bits
in the corresponding input_dev in that hook.
Thanks to Petr Ostadal who was willing to test the driver. The rest of
Cc's listed below had something to do with that driver over the years
in our enterprise tree.

8x5" tablet with 4000LPI resolution and 2048 levels pressure-sensitive
pen manufactured by the Chinese company Huion.
The driver fixes incorrect report descriptor sent by the device,
performs custom initialization required to switch the tablet into

Add a quirk to ignore Jabra speakerphone 410 and 510 devices HID
interface.
On those devices, the USB audio interface is working nicely,
but the HID interface is not working with the kernel usbhid driver,
and it requires a specific userspace program.
We could unbind it from userspace but just attaching the usbhid driver has
sometimes nasty effects:
either confusing the device state machine or triggering a storm of volume key
events making eventual sound UI blinking like crazy.

It looks like the manual merge 0d69a3c731 ("Merge
branches 'for-3.9/sony' and 'for-3.9/steelseries' into for-linus") accidentally
removed Sony RF receiver with USB product id 0x0374 from the "have special

("HID: add support for Sony RF receiver with USB product id 0x0374"). Add the

This driver was originally written by James McKenzie, updated by
Greg Kroah-Hartman, further updated by Bastien Nocera, with suspend
support added.
I ported it to the HID subsystem, in order to simplify it a litle
and allow lirc to use it through hiddev.
More recent versions of the IR receiver are also supported through
a patch by Alex Karpenko. The patch also adds support for the 2nd
and 5th generation of the controller, and the menu key on newer
brushed metal remotes.

This adds the 2nd generation Wii Remote IDs. They have a different
Bluetooth chipset (CSR instead of Broadcom) and are more restrictive in
what they accept as input. Hence, you need up-to-date BlueZ and
Bluetooth HIDP modules to use these devices.

This usb radio device shares USB ID with many Atmel V-USB (and probably other)
devices so patch sorts things out by checking name, vendor, product of hid device.
