2016-10-10HID: add quirk for Akai MIDImix.Steinar H. Gunderson2-0/+4
The Akai MIDImix (09e8:0031) is a MIDI fader controller that speaks regular MIDI and works well with Linux. However, initialization gets delayed due to reports timeout: [3643645.631124] hid-generic 0003:09E8:0031.0020: timeout initializing reports [3643645.632416] hid-generic 0003:09E8:0031.0020: hiddev0: USB HID v1.11 Device [AKAI MIDI Mix] on usb-0000:00:14.0-2/input0 Adding "usbhid.quirks=0x09e8:0x0031:0x20000000" on the kernel command line makes the issues go away.

2016-10-10Revert "HID: dragonrise: fix HID Descriptor for 0x0006 PID"Ioan-Adrian Ratiu1-58/+0
This reverts commit 18339f59c3a6 ("HID: dragonrise: fix HID...") because it breaks certain dragonrise 0079:0006 gamepads. While it may fix a breakage caused by commit 79346d620e9d ("HID: input: force generic axis to be mapped to their user space axis"), it is probable that the manufacturer released different hardware with the same PID so this fix works for only a subset and breaks the other gamepads sharing the PID. What is needed is another more generic solution which fixes 79346d620e9d ("HID: input: force generic axis ...") breakage for this controller: we need to add an exception for this driver to make it keep the old behaviour previous to the initial breakage (this is done in patch 2 of this series).

2016-10-10HID: hid-dr: add input mapping for axis selectionIoan-Adrian Ratiu1-0/+25
Commit 79346d620e9d ("HID: input: force generic axis to be mapped to their user space axis") made mapping generic axes to their userspace equivalents mandatory and some lower end gamepads which were depending on the previous behaviour suffered severe regressions because they were reusing axes and expecting hid-input to multiplex their map to the respective userspace axis by always searching for and using the next available axis. One solution is to add a hid quirk for this type of "previous" behaviour in hid-input to bypass the new axes policy in favour of the old one, but since only one hardware vendor seems to be affected negatively we're better off making and exception and mapping in the driver for now; if more vendors or drivers turn out to experience the problem we should reconsider the quirk solution.

2016-09-27HID: alps: fix multitouch cursor issueMasaki Ota1-6/+6
Issue reproduction procedure: 1. three or more fingers put on Touchpad. 2. release fingers from Touchpad. 3. move the cursor by one finger. 4. the cursor does not move. Cause: We do not notify multi fingers state correctly to input subsystem. For example, when three fingers release from Touchpad, fingers state is 3 -> 0. It needs to notify first, second and third finger's releasing state. Fix this by not breaking out on z axis and move x,y,z input handling code to the correct place so that it's in fact per-finger.

2016-09-26HID: sony: Defer the initial USB Sixaxis output reportFrank Praznik1-4/+25
When initially connected via USB the Sixaxis isn't fully initialized until the PS logo button is pressed and won't send any input reports nor will any state set by output reports be retained. This adds a 'defer_initialization' flag to the sony_sc struct which, when set, will delay sending any output reports until the first input report has arrived. This flag is used with the USB Sixaxis to ensure that any state sent will persist since, until the PS button is pushed, any changes sent to the controller via an output report will be lost after a couple of seconds. The initial state of the controller is still configured at the time of the initial connection and won't be internally modified after that, so any state set by the user between that time and the recepit of the first input report won't be lost.

2016-09-26HID: sony: Relax duplicate checking for USB-only devicesFrank Praznik1-8/+32
Some USB-only devices which masquerade as Sixaxis controllers report the same generic Bluetooth address for all hardware when queried via the HID report. This causes these devices to be wrongly rejected as duplicates when more than one is connected at once. This introduces a connection type comparison when checking for duplicates and only rejects the newly connected device if the existing matching device is connected using a different connection protocol. The results of the connection type comparison are also used when registering power supply info as the device Bluetooth address is used as the unique identifier string. In cases where more than one valid device has the same Bluetooth address the device ID is now appended to the power supply name string to avoid name collisions when registering the power supply information.

While investigating bug https://bugzilla.kernel.org/show_bug.cgi?id=37982 , there was solid evidences that Microsoft reused the same report descriptor for the its Digital Media keyboard series. Since 1989dad "HID: input: ignore System Control application usages if not System Controls", the keyboard series do not produce a spurious joystick input device inode without needing to patch the problematic report descriptor.

2016-09-19HID: input: ignore System Control application usages if not System ControlsBenjamin Tissoires1-0/+9
Microsoft is reusing its report descriptor again and again, and part of it looks like this: 0x05, 0x01, // Usage Page (Generic Desktop) 299 0x09, 0x80, // Usage (System Control) 301 0xa1, 0x01, // Collection (Application) 303 0x85, 0x03, // Report ID (3) 305 0x19, 0x00, // Usage Minimum (0) 307 0x29, 0xff, // Usage Maximum (255) 309 0x15, 0x00, // Logical Minimum (0) 311 0x26, 0xff, 0x00, // Logical Maximum (255) 313 0x81, 0x00, // Input (Data,Arr,Abs) 316 0xc0, // End Collection 318 While there is nothing wrong in term of processing, we do however blindly map the full usage range (it's an array) from 0x00 to 0xff, which creates some interesting axis, like ABS_X|Y, and a bunch of ABS_MISC + n. While libinput and other stacks don't care that much (we can detect them), joydev is very happy and attaches itself to the mouse or keyboard. The problem is that joydev now handles the device as a joystick, but given that we have a HID array, it sets all the ABS_* values to 0. And in its world, 0 means -32767 (minimum value), which sends spurious events to games (think Steam). It looks like hid-microsoft tries to tackle the very same problem with its .report_fixup callback. But fixing the report descriptor is an endless task and is quite obfuscated. So take the hammer, and decide that if the application is meant to be System Control, any other usage not in the System Control range should be ignored.

2016-08-11HID: wacom: Update last_slot_field during pre_report phaseJason Gerecke2-37/+27
If a touchscreen contains both multitouch and single-touch reports in its descriptor in that order, the driver may overwrite information it saved about the format of the multitouch report. This can cause the report processing code to get tripped up and send an incorrect event stream to userspace. In particular, this can cause last_slot_field to be overwritten with the result that the driver prematurely assumes it has finished processing a slot and sending the ABS_MT_SLOT event at the wrong point in time, associating events for the current contact with the following contact instead. To prevent this from occurring, we update the value of last_slot_field durring the pre_report phase to ensure that it is correct for the report that is to be processed.

2016-08-10HID: wacom - add touch_arbitration parameter to wacom modulePing Cheng1-27/+36
Touch arbitration is always on in wacom.ko. However, there are touch enabled applications use both pen and touch simultaneously. We should provide an option for userland to decide if they want arbitration on or off. This patch sets default touch_arbitration to on since most userland apps are not ready to process pen and touch events simultaneously. In the future, when userland is ready to accept pen and touch events together, we will switch default touch_arbitration to off.

The 'oVid' and 'oPid' variables used by wacom_are_sibling are a hacky solution to the problem of the driver historically having few good heuristics to use in determining if two devices should be considered siblings or not. While it works well enough for explicitly supported devices, it offers no help for HID_GENERIC devices. Now that we have a bit more information (e.g. direct/indirect) available to us though, we should make use of it it to improve the pairing of such devices.

"Direct" input devices like Cintiqs and Tablet PCs set the INPUT_PROP_DIRECT property to notify userspace that the sensor and screen are overlaid.

2016-08-05HID: wacom: power_supply: mark the type as USBBenjamin Tissoires1-1/+1
When upowerd detects a new device, it tries to map this new device to an input to guess its kind. It works OK for wired tablets when the wireless module and its battery are attached, but not so well when connected over wireless. In that case, the battery is attached to the wireless HID node, not the Pen or Pad HID node. So there is no input node as a parent of the reported battery, which means it will be showed as a computer battery in gnome-control-center. If we set the power supply type to USB, upowerd has a heuristic that detects "wacom_" in the name of the power_supply, and set the type to tablet. So it's now clear that the reported battery of from a tablet.
