3bce6f981a HID: ADS/Tech Radio si470x needs blacklist entry
This patch adds blacklist entries in hid-quirks.c to let the usbhid driver
ignore the si470x radio devices. They are now handled by the new radio-si470x
driver.

d7d32c815b HID: Refactor MS Presenter 8K key mapping
Following the suggestion of Jonas, this patch maps the special keys of
the MS Presenter 8000 to targets that should allow for better re-mapping
according to individual use cases (i.e. I avoided hard-wiring to
standard keys). This time I also included the last missing key event
(switching back from presentation mode).

The optimal Xmodmap customization for using the Presenter with
OpenOffice now looks like this for me:

keycode 175 = Escape
keycode 179 = F5
keysym XF86Forward = Right
keysym XF86Back = Left

fe56caa97e HID: Support Samsung IR remote
Samsung USB remotes (0419:0001) are rejected by kernel 2.6.23, because the
report descriptor from the remote contains a 48 bit HID report field. HID 1.11
states: Fields may span at most 4 bytes.

This patch, based on 2.6.23, fixes this by modifying the internal report
descriptor in hid-quirks.c. Additional user space support (e.g. LIRC) is
required to fetch the information from the hiddev interface.

The burden to reconstruct the data is moved into userspace (lirc through hiddev).
There is no need to set HID_QUIRK_HIDDEV quirk, as the device has also output
applications, which trigger the creation of hiddev device automatically.

The WARN_ON() in implement() and extract() spit out stacktraces and
a lot of other information that might make users think that there is
something seriously wrong with the system. WARN_ON() should not be

0887b4cb21 HID: force hiddev creation for SONY PS3 controller
The device is not discoverable, and needs to be poked to set its master, the
Bluetooth device it will try to connect to when the "Home" button is pressed
without a cable plugged in.

Using libusb means disconnecting the device from its driver to get the report
descriptor. Using hiddev, we can poke it without relinquishing control over it,
so when you plug it in, it would still work as a pad.

This could be then used by sixpair program, after it is rewritten to use
hiddev instead of libusb.

36ccaad640 HID: hid-input quirk for BTC 8193
BTC 8193 keyboard handles its scrollwheel in very non-standard way.
It produces two non-standard usages for scrolling up and down, in
both cases with postive value equaling to 1. We handle this by temporary
mapping, which we then catch in quirk event handler, and remap to
negative HWHEEL even in order to introduce correct behavior.

Also the button requires special mapping, as it triggers standard-violating
usage code.

86166b7bcd HID: add hidraw interface
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.

Note that Apple calls this receiver 'IRController4' (info taken

was previously removed, because it caused unnecessary storm of events in cases
of positioning devices, etc.

This patch adds reporting of usage codes as EV_MSC events only for key events.
We issue the EV_MSC event only if the state of the key corresponding to the
given code has changed, so that we don't report usages that are sent in every
report even if the state hasn't changed (for example Shift/Caps Lock/...
states as sent by various keyboards).

This functionality is required at least by KeyTouch in order to provide
convenient means for remapping the usage codes.

82eb121989 HID: ignore all non-LED usages in output fields in hid-input
We have to ignore all non-LED usages in output fields if the
report descriptor of the device specifies any. If we don't do
so, the devices which contain the same usages both in input and
output reports with different parameters will mess things up. In
hid-input, we currently care only for the input usages, with exception
for LEDs. All other output usages should be properly handled by
appropriate force-feedback driver.

Fixes auto-calibration for Saitek Cyborg Evo Force joystick.
