There are some devices (for example Dell Multimedia Keyboard SK-8135) that have
a volume control knob which generates relative events instead of absolute.
hid-input maps them to ABS_VOLUME. HUT pages don't restrict volume to absolute
values.

Adding REL_VOLUME doesn't seem feasible, nothing knows how to handle it. This
patch translates relative ABS_VOLUME events into appropriate number of series
of VOLUME_UP or VOLUME_DOWN events respectively, so that userspace sees the
correct values in the end.

This keyboard has wireless mouse which has left, middle, right buttons and
2-dimensional scrolling wheel.  Unfornetuly, this wheel reports side scrolling
events and 11 or 12 button events at the same time.

I've wrote a patch to fix this mapping.  I'm not sure if this mapping is proper
for buttons, because , for example, there is no entry for "burn cd" in input.h.

The patch also supress 11 and 12 button events from mouse when you scroll the
wheel left and right.  With this patch, only side scrolling events are
reported.  (This mouse has only 4 buttons and 2D wheel. There is no such
buttons like 11 and 12.)

Petalynx Maxter remote control [1] 0x18b1/0x0037 emits 0xfa and 0xfc from
consumer page (reserved in HUT 1.12) for back and more keys. It also emits
a few usages from LOGIVENDOR page, which need adding.

Also, this device has broken report descriptor - the reported maximum is too
low - it doesn't contain the range for 'back' and 'more' keys, so we need to
bump it up before the report descriptor is being parsed.

Besides all this, it also requires NOGET quirk.

This patch does so.

When comparing usb vs ps2 / testing the keycodes generated for the easy access
keys on my trust (microsoft compatible) keyboard. I noticed the search key
generated the keycode for find when connected through USB. This lead me to
check the consumer page mappings in hid-input.c . And it turns out the the
mapping for ID 0x221 deviates from the HUT standard document:
http://www.usb.org/developers/devclass_docs/Hut1_12.pdf

Currently it is incorrectly mapped to find, whereas it should be mapped to
search. I also added missing bindings for ID 0x21f, the real find and for
0x222, goto.

Microsoft SideWinder GameVoice driver is a trivial device with a few buttons
(0x09 HID usage) and an audio connector, which just forwards the audio input
into oridinary sound card present in the computer.

Despite this fact, the only interface of this device reports itself as a
Telephony/Headset type of HID device. This is apparently incorrect - the device
itself doesn't provide any audio/telephony functionality. This is achieved in
userland application which only needs to receive the button events from the HID
driver.

This patch establishes a new quirk which forces hid-input to claim a device it
will otherwise leave untouched.

Chicony KU-0418 (aka Saitek PZ08AU gaming keyboard) has a separate
"tactical pad" with 11 non-functional buttons - they generate usage
codes from 0xff00 (MSVENDOR) usage page. Special case handling for
this keyboard added, so no later clash with MSVENDOR mappings is going
to occur.

There have been many reports recently about broken HID devices, the
diagnosis of which required users to recompile their kernels in order
to be able to provide debugging output needed for coding a quirk for
a particular device.

This patch makes CONFIG_HID_DEBUG default y if !EMBEDDED and makes it
possible to control debugging output produced by HID code by supplying
'debug=1' module parameter.
