2010-03-09Input: scancode in get/set_keycodes should be unsignedDmitry Torokhov1-12/+12
The HID layer has some scan codes of the form 0xffbc0000 for logitech devices which do not work if scancode is typed as signed int, so we need to switch to unsigned it instead. While at it keycode being signed does not make much sense either.

2010-01-04HID: handle joysticks with large number of buttonsJiri Kosina1-1/+6
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.

2009-06-12HID: use debugfs for report dumping descriptorJiri Kosina1-12/+1
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. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

It's implemented to change behaviour in very tiny manner, so that no driver needs to be changed this time. Also add generic drivers for both usb and bt into usbhid or hidp respectively which will bind all non-blacklisted device.

2008-05-20HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN.Diego 'Flameeyes' Petteno1-2/+3
Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for non-laptop Apple keyboards of the Aluminium series. The USB version of these don't need Numlock emulation, like the laptop (and Aluminium Wireless) do, as they have a proper keypad. This patch splits the Numlock emulation for Apple keyboards in a different quirk flag, so that it can be enabled for all the keyboards but the Aluminium USB ones. If the Numlock emulation is enabled for Aluminium USB keyboards, the JKL and UIO keys become the numeric pad, and the rest of the keyboard is disabled, included the key used to disable Numlock. Additionally, these keyboard should not have a Numlock at all, as the Numlock key is instead replaced by the 'Clear' key as usual for Apple USB keyboards.

The MS Presenter 8000 bluetooth mouse is a "dual-use" device: If you press a button on the top, you can turn it around and find special keys on the other side, useful for presentations.

2007-10-14HID: enable hiddev for the SantaRosa MacBookPro IR receiverStelian Pop1-0/+3
The infrared remote receiver found in the SantaRosa MacBookPro laptops (MacBookPro3,1) need to be forced to expose a HIDDEV interface (instead of HIDINPUT) so that lirc can access it using the 'macmini' driver. The patch below adds the required quirk for forcing the HIDDEV interface to be activated (HID_QUIRK_HIDDEV) and introduces a new quirk which forces the HIDINPUT interface to be ignored (HID_QUIRK_IGNORE_HIDINPUT). Note that Apple calls this receiver 'IRController4' (info taken from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem to all use the 'IRController1' device (USB id 05ac:8240) which doesn't need those quirks.

2007-10-14HID: Report usage codes of keys as EV_MSC scancode eventsJiri Kosina1-0/+8
Current HID layer does not report usage codes to the input layer. This feature 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.

2007-10-14HID: ignore all non-LED usages in output fields in hid-inputJiri Kosina1-0/+7
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.

This keyboard emits a few usages that are not handled properly by hid-input. The usages from MSVENDOR page are colliding with Chicony Tactical Pad device, so we have to distinguish in runtime. Ugly ... Also, the buttons 1-5 have to be handled in a non-standard way, as they are emitted by the keyboard in a bitfield-like fashion, but the field is not presented as bit-field by the keyboard. The keys can't be pressed simultaneously, so the handling we have is correct. This patch also extends hid_keyboard[] with KPLeftParenthesis and KPRightParenthesis as defined by Keyboard page in HUT 1.12. The corresponding usages are also emitted by this keyboard.

2007-07-09HID: handle cases of volume knobs generating relative valuesJiri Kosina1-0/+25
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. kernel.org bugzilla 5233 Reported-by: Jochen Eisinger <jochen@penguin-breeder.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

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.

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.

2007-07-09HID: force hid-input for Microsoft SideWinder GameVoice deviceJiri Kosina1-1/+1
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.
