Add HID_QUIRK_HIDDEV for the Belkin Flip USB KVM, which provides for software
control of switching via a HID class interface. It overloads three HID LED

doesn't make sense to map. In order to force the creation of a hiddev device
for controlling the Flip, this quirk flag is needed.

The USB HID driver fails to reset its error-retry timeout when there
has been a long time interval between I/O errors with no successful URB
completions in the meantime.  As a result, the very next error would
trigger an immediate reset, even if it was a chance event occurring
long after the previous error.

More USB keyboards and mice than one might expect end up getting I/O
errors. Almost always this results from hardware problems of one sort of
another. For example, people attach the device to a USB extension cable,
which degrades the signal.  Or they simply have poor quality cables to
begin with. Or they use a KVM switch which doesn't handle USB messages
correctly. Etc...

There have been reports from several users in which these I/O
errors would occur more or less randomly, at intervals ranging from
seconds to minutes.  The error-handling code in hid-core.c was originally
meant for situations where a single outage would persist for a few hundred
ms (electromagnetic interference, for example).  It didn't work right when
these more sporadic errors occurred, because of a flaw in the logic
which this patch fixes.

This patch (as873) fixes that oversight.

Dongle shipped with Logitech DiNovo Edge (0x046d/0xc714) behaves in a weird
non-standard way - it contains multiple reports with the same usage, which
results in remapping of GenericDesktop.X and GenericDesktop.Y usages to
GenericDesktop.Z and GenericDesktop.RX respectively, thus rendering the
touchwheel unusable.

The commit 35068976 solved this
in a way that it didn't remap certain usages. This however breaks
(at least) middle button of Logic3 / SpectraVideo (0x1267/0x0210),
which in contrary requires the remapping.

To make both of the harware work, allow remapping of these usages again,
and introduce a quirk for Logitech DiNovo Edge "touchwheel" instead - we
disable remapping for key, abs and rel events only for this hardware.

This patch makes extra keys (F1-F12 in special mode, zooming, rotate, shuffle)
on Logitech S510 keyboard work.

Logitech S510 keyboard sends in report no. 3 keys which are far above the
logical maximum described in descriptor for given report.

This patch introduces a HID quirk for this wireless USB receiver/keyboard
in order to fix the report descriptor before it's being parsed - the logical
maximum and the number of usages is bumped up to 0x104d). The values are in the
"Reserved" area of consumer HUT, so HID_MAX_USAGE had to be changed too.

In addition to proper extracting of  the values from report descriptor, proper
HID-input mapping is introduced for them.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Add new quirk HID_QUIRK_SKIP_OUTPUT_REPORTS to skip output reports
when enumerating reports on a hid-input device. Add this quirk and

PantherLord Twin USB Joystick, 0810:0001 has separate input reports
for 2 distinct game controllers in the same interface, so it needs
HID_QUIRK_MULTI_INPUT. However, the device also contains one output
report per controller which is used to control the force feedback
function, and we do not want those to appear as separate input
devices as well. The simplest approach seems to be to add a quirk to
skip output reports on 0810:0001, and allow the force feedback

After:
> # readlink -f /sys/class/input/input3/event3/device
> /sys/devices/pci0000:00/0000:00:10.0/usb1/1-1

This causes breakage:
