It is observed that the Magic Mouse 2 would not enter multi-touch mode unless the mouse is connected before loading the module. It seems to be a quirk specific to Magic Mouse 2 Retrying after 500ms fixes the problem for me. The delay can't be reduced much further --- 300ms didn't work for me.

2021-04-07HID: magicmouse: fix 3 button emulation of Mouse 2John Chen1-0/+18
It is observed that, with 3 button emulation, when middle button is clicked, either the left button or right button is clicked as well. It is caused by hidinput "correctly" acting on the event, oblivious to the 3 button emulation. As raw_event has taken care of everything, no further processing is needed. However, the only way to stop at raw_event is to return an error (negative) value. Therefore, the processing is stopped at event instead.

2021-04-07HID: lenovo: Add support for Thinkpad X1 Tablet Thin keyboardHans de Goede1-0/+61
The Thinkpad X1 Tablet Thin keyboard's HID interface for the media-keys and other special functions, is quite similar to the Thinkpad 10 ultrabook keyboard's mouse/media-keys HID interface. The only difference is that it needs a bit different key mappings. Add support for the mute-LED and the non-standard media-keys on this keyboard by re-using the tp10_ultrabook_kbd code combined with a new lenovo_input_mapping_x1_tab_kbd() function.

Instead of looking for a hdev with a type of HID_TYPE_USBMOUSE find the interface for the mute/mic-mute/fn-lock LEDs by checking for the output-report which is used to set them. This is a preparation patch for adding support for the LEDs on the X1 tablet thin keyboard which uses the same output-report, but has a separate (third) USB interface for the touchpad/mouse functionality.

2021-04-07HID: lenovo: Set default_triggers for the mute and micmute LEDsHans de Goede1-0/+2
The mute and mic-mute LEDs should be automatically turned on/off based on the audio-card's mixer settings. Add the standardized default-trigger names for this, so that the alsa code can turn the LEDs on/off as appropriate (on supported audio cards). This brings the mute/mic-mute LED support inline with the thinkpad_acpi support for the same LEDs in keyboards directly connected to the laptop's embedded-controller.

2021-04-07HID: lenovo: Map mic-mute button to KEY_F20 instead of KEY_MICMUTEHans de Goede1-3/+6
Mapping the mic-mute button to KEY_MICMUTE is technically correct but KEY_MICMUTE translates to a scancode of 256 (248 + 8) under X, which does not fit in 8 bits, so it does not work. Because of this userspace is expecting KEY_F20 instead, theoretically KEY_MICMUTE should work under Wayland but even there it does not work, because the desktop-environment is listening only for KEY_F20 and not for KEY_MICMUTE.

2021-04-07HID: lenovo: Check hid_get_drvdata() returns non NULL in lenovo_event()Hans de Goede1-0/+3
The HID lenovo probe function only attaches drvdata to one of the USB interfaces, but lenovo_event() will get called for all USB interfaces to which hid-lenovo is bound. This allows a malicious device to fake being a device handled by hid-lenovo, which generates events for which lenovo_event() has special handling (and thus dereferences hid_get_drvdata()) on another interface triggering a NULL pointer exception. Add a check for hid_get_drvdata() returning NULL, avoiding this possible NULL pointer exception.

Fix the following issues with lenovo_led_set_tp10ubkbd() error handling: 1. On success hid_hw_raw_request() returns the number of bytes sent. So we should check for (ret != 3) rather then for (ret != 0). 2. Actually propagate errors to the caller. 3. Since the LEDs are part of an USB keyboard-dock the mute LEDs can go away at any time. Don't log an error when ret == -ENODEV and set the LED_HW_PLUGGABLE flag to avoid errors getting logged when the USB gets disconnected.

2021-03-30HID: surface-hid: Add support for legacy keyboard interfaceMaximilian Luz3-0/+315
Add support for the legacy keyboard (KBD/TC=0x08) HID transport layer of the Surface System Aggregator Module (SSAM) to the Surface HID driver. On Surface Laptops 1 and 2, this interface is used to connect the integrated keyboard. Note that this subsystem interface essentially provides a limited HID transport layer. In contrast to the generic HID interface (TC=0x15) used on newer Surface models, this interface only allows (as far as we know) for a single device to be connected and is otherwise severely limited in terms of support for feature- and output-reports. Specifically, only caps-lock-LED output-reports and a single read-only feature-report are supported.

2021-03-30HID: Add support for Surface Aggregator Module HID transportMaximilian Luz7-0/+640
Add a HID transport driver to support integrated HID devices on newer Microsoft Surface models (specifically 7th-generation, i.e. Surface Laptop 3, Surface Book 3, and later). On those models, the internal keyboard and touchpad (as well as some other HID devices with currently unknown function) are connected via the generic HID subsystem (TC=0x15) of the Surface System Aggregator Module (SSAM). This subsystem provides a generic HID transport layer, support for which is implemented by this driver.

2021-03-19HID: support for initialization of some Thrustmaster wheelsDario Pagani4-3/+378
Add support for proper initialization of some Thrustmaster wheels that appear like a "Thrustmaster FFB Wheel" (044f:b65d) to the host. When the device is connected a special usb request is sent, this request makes the wheel disconnect and reappear to the host as the "real wheel". For example: a T150 will re-appear as 044f:b677 and a T300 as 044f:b66e [jkosina@suse.cz: renamed driver to hid-thrustmaster] Link: https://github.com/scarburato/hid-tminit Signed-off-by: Dario Pagani <dario.pagani.146@gmail.com> Co-developed-by: Kim Kuparinen <kimi.h.kuparinen@gmail.com> Signed-off-by: Kim Kuparinen <kimi.h.kuparinen@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2021-03-16HID: wacom: set EV_KEY and EV_ABS only for non-HID_GENERIC type of devicesPing Cheng1-4/+2
Valid HID_GENERIC type of devices set EV_KEY and EV_ABS by wacom_map_usage. When *_input_capabilities are reached, those devices should already have their proper EV_* set. EV_KEY and EV_ABS only need to be set for non-HID_GENERIC type of devices in *_input_capabilities. Devices that don't support HID descitoprs will pass back to hid-input for registration without being accidentally rejected by the introduction of patch: "Input: refuse to register absolute devices without absinfo" Fixes: 6ecfe51b4082 ("Input: refuse to register absolute devices without absinfo") Signed-off-by: Ping Cheng <ping.cheng@wacom.com> Reviewed-by: Jason Gerecke <Jason.Gerecke@wacom.com> Tested-by: Juan Garrido <Juan.Garrido@wacom.com> CC: stable@vger.kernel.org Signed-off-by: Jiri Kosina <jkosina@suse.cz>
