14bf62cde7 HID: add driver for Roccat Kone gaming mouse
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.

e639ba481b HID: avoid '\0' in hid debugfs events file
When dumping /sys/kernel/debug/hid/$device/events '\0' characters show up
(invisible if cat to console but shown by less or while looking at a dump
 file).  These are due to hid_debug_event() adding strlen()+1 bytes to the ring
buffer (e.g. including the trailing '\0').  Any roll-over causes a '\0' as well
as hid_debug_event() handles the ring buffers with HID_DEBUG_BUFSIZE-1 size
while hid_debug_events_read() handles it with full HID_DEBUG_BUFSIZE size.

dbf2b17de5 HID: hid-ntrig: multitouch cleanup and fix
This cleans up the identification of multitouch groups and enables
the end of group sync.

Taps are now explicitly handled to adjust for the changes in the
event stream in multitouch mode.  Added triple and quad tap for the
benefit of tools that recognize different tap types but do not have
full multi touch support.

This cleans up the behavior particularly for the latest firmware, which
didn't work particularly well with the older version of the driver.

In this form, when multitouch is active, both mt and st events will come out of
the "N-Trig MultiTouch" device.  And when its not st events will come out of
"N-Trig Touchscreen".

128537cea4 HID: add a device driver for the Apple Magic Mouse.
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.

Some user-space tools to talk to the mouse directly (that is, when it is not
associated with the host's HIDP stack) are at

2dbf209d7a HID: make full-fledged hid-bus drivers properly selectable
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.

d4bfa033ed HID: make raw reports possible for both feature and output reports
In commit 2da31939a4 ("Bluetooth: Implement raw output support for HIDP
layer"), support for Bluetooth hid_output_raw_report was added, but it
pushes the data to the intr socket instead of the ctrl one. This has been
fixed by 6bf8268f9a ("Bluetooth: Use the control channel for raw HID reports")

Still, it is necessary to distinguish whether the report in question should be
either FEATURE or OUTPUT. For this, we have to extend the generic HID API,
so that hid_output_raw_report() callback provides means to specify this
value so that it can be passed down to lower level hardware drivers (currently
Bluetooth and USB).

1c3a02c215 HID: add NOGET quirk for Prodige Cordless Combo
I happen to own a keyboard identified as 05af:3062 which is labeled as
"FlatX Coldless Combo" by "Prodige", which exhibits input problems without
NOGET quirk. For some reason, lsusb reports this device as "Jing-Mold
Enterprise Co., Ltd", which is not mentioned anywhere on the package.
A quick search on the intenet shows that there a other people who have
this in their lsusb output, but apparently they don't have the problem
I am seeing (or they are not such furious typists as myself).

4bb9508bbb HID: remove TENX iBuddy from blacklist
There were multiple reports which indicate that vendor messed up horribly
and the same VID/PID combination is used for completely different devices,
some of them requiring the blacklist entry and other not.

Remove the blacklist entry for this combination of VID/PID completely, and let
the user decide and unbind the driver via sysfs eventually, if needed. Proper
fix would be fixing the vendor.

54a6593d65 HID: allow disabling hard-coded ISO-layout for Apple keyboards
This patch adds a new option named "iso_layout" to the driver
"hid-apple.ko", to allow disabling of the hard-coded ISO-layout.

Disabling the hard-coded layout solves the problem that the kernel-module only
works perfectly for the english/american version of the Apple aluminum
keyboard. Other versions have swapped keys, e.g. the "<"-key  is swapped with
"^"-key on the german keyboard. There is a very long bug-entry on Launchpad to
this problem:

cf2f765f18 HID: handle joysticks with large number of buttons
Current HID code doesn't properly handle HID joysticks which have
larger number of buttons than what fits into current range reserved
for BTN_JOYSTICK.

One such joystick reported to not work properly is Saitek X52 Pro
Flight System.

We can't extend the range to fit more buttons in, because of backwards
compatibility reasons.

Therefore this patch introduces a new BTN_TRIGGER_HAPPY range, and
uses these to map the buttons which are over BTN_JOYSTICK limit.

5b915d9e6d HID: fixup quirk for NCR devices
NCR devices are terminally broken by design -- they claim themselves to contain
proper input applications in their HID report descriptor, but behave very badly
if treated in standard way.

According to NCR developers, the devices get confused when queried for reports
in a standard way, rendering them unusable.

NCR is shipping application called "RPSL" that can be used to drive these
devices through hiddev, under the assumption that in-kernel driver doesn't
perform initial report query.
If it does, neither in-kernel nor hiddev-based driver can operate with these
devices any more.

Introduce a quirk that skips the report query for all NCR devices. The previous
NOGET quirk was wrong and had been introduced because I misunderstood the nature
of brokenness of these devices.

affbb8c6e6 HID: support larger reports than 64 bytes in hiddev
hiddev userspace driver uses a rignbuffer to store the parsed usages
that should be returned through read(). This buffer is 64 bytes long,
which is sufficient for queueing single USB 1.0 low-speed report, which
is of maximum size 48 bytes.

There are however USB HID devices which are full-speed USB devices, and
therefore they are free to produce reports 64 bytes long. This is correctly
handled by HID core, but read() on hiddev node gets stuck forever, because
the ring buffer loops infinitely (as it is exactly 64 bytes long as well),
never advancing the buffer pointer.

Plus, the core driver is ready to handle highspeed devices, so we should be
able to handle reports from such devices in the hiddev driver as well, which
means we need larger ringbuffer.

0810b51170 HID: Support new variants of Samsung USB IR receiver (0419:0001)
This patch extends the existing Samsung IrDA (0419:0001) quirk file with newly
reported variants:

* New device variants with 203 byte and 135 byte report descriptors were
  reported to be recognized incorrectly. This patch adds an autodetection for
  those two, using report descriptor size to enable new quirks.

* Any other unknown 0419:0001 variants will now be treated without any quirk
  flags (i.e. IGNORE_HIDINPUT/HIDDEV_FORCE will not be set by default anymore).

More details:

1. Descriptor size 184 bytes ("Satelco bundled remote")
Already supported since kernel 2.6.25 (my old patch).

2. Descriptor size 203 bytes ("Optronix remote")
This receiver mostly works with the regular HID input driver. Only when some
keys are released, another spurious key press event is interpreted due to
incorrect array ranges. According to HID 1.11, section 6.2.2.5, arrays should
return a 0 value when no control is asserted, and ranges should go from 1 to
the number of elements. The patch clips the value with a logical range from
1..15 (instead of originally 0..18).

Ticket with more information available at
https://bugs.launchpad.net/bugs/326986

3. Descriptor size 135 bytes ("Gotview remote")
This receiver has a similar issue than the previous one, i.e. it mostly works
with regular HID input, except some key press events get stuck on key release.
The patch clips the array value from 1..14 (instead of originally 0..17).

Ticket with more information available at
http://bugs.archlinux.org/task/15216

4. Other unknown variants (found one report with 218 bytes,
   but no further information about issues)

For such unknown variants we should refrain from changing any device flags.
Currently, HIDINPUT is suppressed and HIDDEV is enforced (because in 2.6.25 the
quirk table did not yet allow differentiating variants and we
did not expect variants either). Now we should be as strict as
possible and enable it only for the first variant above.

cd667ce247 HID: use debugfs for events/reports dumping
This is a followup patch to the one implemeting rdesc representation in debugfs
rather than being dependent on compile-time CONFIG_HID_DEBUG setting.

The API of the appropriate formatting functions is slightly modified -- if
they are passed seq_file pointer, the one-shot output for 'rdesc' file mode
is used, and therefore the message is formatted into the corresponding seq_file
immediately.

Otherwise the called function allocated a new buffer, formats the text into the
buffer and returns the pointer to it, so that it can be queued into the ring-buffer
of the processess blocked waiting on input on 'events' file in debugfs.

'debug' parameter to the 'hid' module is now used solely for the prupose of inetrnal
driver state debugging (parser, transport, etc).

a635f9dd83 HID: use debugfs for report dumping descriptor
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.

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

e43bd67d72 HID: fix race between usb_register_dev() and hiddev_open()
upon further thought this code is still racy.

	retval = usb_register_dev(usbhid->intf, &hiddev_class);

here you open a window during which open can happen

	if (retval) {
		err_hid("Not able to get a minor for this device.");
		hid->hiddev = NULL;
		kfree(hiddev);
		return -1;
	} else {
		hid->minor = usbhid->intf->minor;
		hiddev_table[usbhid->intf->minor - HIDDEV_MINOR_BASE] = hiddev;

and will fail because hiddev_table hasn't been updated

The obvious fix of using a mutex to guard hiddev_table doesn't work because
usb_open() and usb_register_dev() take minor_rwsem and we'd have an AB-BA
deadlock. We need a lock usb_open() also takes in the right order and that leaves
only one option, BKL. I don't like it but I see no alternative.

Once the usb_open() implements something better than lock_kernel(), we could also
do so.

0361a28d3f HID: autosuspend support for USB HID
This uses the USB busy mechanism for aggessive autosuspend of USB
HID devices. It autosuspends all opened devices supporting remote wakeup
after a timeout unless

- output is being done to the device
- a key is being held down (remote wakeup isn't triggered upon key release)
- LED(s) are lit
- hiddev is opened

As in the current driver closed devices will be autosuspended even if they
don't support remote wakeup.

The patch is quite large because output to devices is done in hard interrupt
context meaning a lot a queuing and locking had to be touched. The LED stuff
has been solved by means of a simple counter. Additions to the generic HID code
could be avoided. In addition it now covers hidraw. It contains an embryonic
version of an API to let the generic HID code tell the lower levels which
capabilities with respect to power management are needed.

60aa49243d Rationalize fasync return values
Most fasync implementations do something like:

     return fasync_helper(...);

But fasync_helper() will return a positive value at times - a feature used
in at least one place.  Thus, a number of other drivers do:

     err = fasync_helper(...);
     if (err < 0)
             return err;
     return 0;

In the interests of consistency and more concise code, it makes sense to
map positive return values onto zero where ->fasync() is called.

96fe2ab830 HID: fix waitqueue usage in hiddev
DECLARE_WAITQUEUE doesn't initialize the wait descriptor's task_list
to 'empty' but to zero.

prepare_to_wait() will not enqueue the descriptor to the waitqueue and
finish_wait() will do list_del_init() on a list head that contains
NULL pointers, which oopses.

This was introduced by 079034073 "HID: hiddev cleanup -- handle all
error conditions properly".

The prior code used an unconditional add_to_waitqueue() which didn't
care about the wait descriptor's list head and enqueued the thing
unconditionally.

The new code uses prepare_to_wait() which DOES check the prior list
state, so use DEFINE_WAIT instead.

011b15df46 USB: change interface to usb_lock_device_for_reset()
This patch (as1161) changes the interface to
usb_lock_device_for_reset().  The existing interface is apparently not
very clear, judging from the fact that several of its callers don't
use it correctly.  The new interface always returns 0 for success and
it always requires the caller to unlock the device afterward.

The new routine will not return immediately if it is called while the
driver's probe method is running.  Instead it will wait until the
probe is over and the device has been unlocked.  This shouldn't cause
any problems; I don't know of any cases where drivers call
usb_lock_device_for_reset() during probe.

the tablet appears to be a single input device that reports the

- thread safety by locking in read & ioctl, introducing a per device mutex
- race between ioctl and disconnect, introducing a flag and locking
  in form of a per low level device mutex
- race between open and other methods, making sure only successfully
  opened devices are put on the list, changing order of events
- range checking both upper and lower limits of the minor range
- make sure further calls to open fail for unplugged devices even if
  the device still has opened files
- error checking for low level open
- possible loss of wakeup events, using standard waiting macros
- race in initialisation by moving registration after full initialisation

6bbe586fd4 HID: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

08ef08ee8c HID: automatically call usbhid_set_leds in usbhid driver
This patch (as1146c) makes usbhid automatically call usbhid_set_leds()
for any device that supports the keyboard boot protocol.

In theory this should be perfectly safe.  BIOSes send the LED output
report as part of their normal device initialization, so any keyboard
device supporting the boot protocol has to be able to handle it.

As a side effect, the hid-dell and hid-bright drivers are no longer
needed, and the Logitech keyboard driver can be removed from hid-lg.

So let's keep our lives simple - let __fput() check FASYNC in

This patch (as1157) adds a no-name PS/2-to-USB keyboard+mouse adapter

"Set-LEDs" report to be sent to the device, without which it won't
send any keystroke information.  Several bug reports mentioning this
device have been filed in various forums; the patch should resolve
them.

This is just a temporary stop-gap for 2.6.28.  A later patch for
2.6.29 will introduce a more generic mechanism for "Set-LEDs", making
this change (and the entire hid-dell driver) unnecessary.

originally testing this. Testing on another system shows that the

b36299bcc0 HID: fix default building of HID-quirk drivers
Commit 9be7bbd54d
(HID: build drivers for all quirky devices by default)
made a wrong assumption about select/depends interaction in Kconfig,
resulting in possibility of link failure with certain configuration
options.

Fix this by explicitly having all the quirk-drivers depend on
USB_HID, default to y and make the possibility to alter the
settings dependent on EBMEDDED.

Once kernel configuration has CONFIG_HID turned on, let also all the
specialized drivers for quirky devices to be built (unless CONFIG_EMBEDDED is
specified), as usually users don't care that much which driver
gives them the functionality, but when they want generic support, they
probably want to have support for all the quirky devices as well.

f129ea6d1e HID: fix a lockup regression when using force feedback on a PID device
Commit 8006479c9b introduced a spinlock in
input_dev->event_lock, which is locked when handling input events.
However, the hid-pidff driver sleeps when handling events as it waits for
reports being sent to the device before changing the report contents
again.
This causes a system lockup when trying to use force feedback with a PID
device, a regression introduced in 2.6.24 and 2.6.23.15.

Fix it by extracting the raw report data from struct hid_report
immediately when hid_submit_report() is called, therefore allowing
drivers to change the contents of struct hid_report immediately without
affecting the already-queued transfer.

In hid-pidff, re-add the removed usbhid_wait_io() to
pidff_erase_effect() instead, to prevent a full report queue from causing
the submission to fail, thus not freeing up device memory.
pidff_erase_effect() is not called while dev->event_lock is held.

c0bd6a4298 HID: remove ignore quirk for MGE UPS devices
This patch reverts the change made four years ago here:
http://www.vg.kernel.org/pub/linux/kernel/people/gregkh/usb/2.4/usb-hid-2.4.25-pre7.patch

UPS's made by MGE can be used with usbhid just fine, and by removing the
ignore quirk allows them to be used with HAL so they just work when plugged
in, without needing to be manually configured.

With the ignore quirk in place a user would have to configure NUT before the
UPS could be used, as NUT uses it's own internal USB matching framework
to match against the USB devices, do low level control messages on the
device and then parse the HID tables all in userspace.

This is not needed, as allowing the device to be claimed as a usbhid device
allows it to be used like any other USB UPS device. The devices correctly
advertise the power device page which can be queried for the device state.

I assume the quirk was changed so that people using < libusb 0.1.8 could
still use NUT's internal HID code to manage the UPS.
libusb 0.1.8 was released quite some time ago: 2004-02-11.

This patch does not break NUT as in drivers/libusb.c the device is force
unbound from the kernel driver using usb_detach_kernel_driver_np () where
it can be controlled like normal.
