2015-02-23HID: microsoft: Add ID for NE7K wireless keyboardJakub Sitnicki
Microsoft Natural Wireless Ergonomic Keyboard 7000 has special My Favorites 1..5 keys which are handled through a vendor-defined usage page (0xff05). Apply MS_ERGONOMY quirks handling to USB PID 0x071d (Microsoft Microsoft 2.4GHz Transceiver V1.0) so that the My Favorites 1..5 keys are reported as KEY_F14..18 events.

2015-02-23HID: i2c-hid: Limit reads to wMaxInputLength bytes for input eventsSeth Forshee
d1c7e29e8d27 (HID: i2c-hid: prevent buffer overflow in early IRQ) changed hid_get_input() to read ihid->bufsize bytes, which can be more than wMaxInputLength. This is the case with the Dell XPS 13 9343, and it is causing events to be missed. In some cases the missed events are releases, which can cause the cursor to jump or freeze, among other problems. Limit the number of bytes read to min(wMaxInputLength, ihid->bufsize) to prevent such problems.

2015-02-17HID: i2c-hid: The interrupt should be level sensitiveMika Westerberg
The Microsoft HID over I2C specification says two things regarding the interrupt: 1) The interrupt should be level sensitive 2) The device keeps the interrupt asserted as long as it has more reports available. We've seen that at least some Atmel and N-Trig panels keep the line low as long as they have something to send. The current version of the driver only detects the first edge but then fails to read rest of the reports (as the line is still asserted). Make the driver follow the specification and configure the HID interrupt to be level sensitive. The Windows HID over I2C driver also seems to do the same.

2015-01-26HID: pidff: Fix initialisation forMicrosoft Sidewinder FF Pro 2Jim Keir
The FF2 driver (usbhid/hid-pidff.c) sends commands to the stick during ff_init. However, this is called inside a block where driver_input_lock is locked, so the results of these initial commands are discarded. This behavior is the "killer", without this nothing else works. ff_init issues commands using "hid_hw_request". This eventually goes to hid_input_report, which returns -EBUSY because driver_input_lock is locked. The change is to delay the ff_init call in hid-core.c until after this lock has been released. Calling hid_device_io_start() releases the lock so the device can be configured. We also need to call hid_device_io_stop() on exit for the lock to remain locked while ending the init of the drivers.

It appears that the Cintiq Companion Hybrid does not send an ABS_MISC event to userspace when any of its ExpressKeys are pressed. This is not strictly necessary now that the pad exists on its own device, but should be fixed for consistency's sake. Traditionally both the stylus and pad shared the same device node, and xf86-input-wacom would use ABS_MISC for disambiguation. Not sending this causes the Hybrid to behave incorrectly with xf86-input-wacom beginning with its 8f44f3 commit.

2015-01-09HID: logitech-hidpp: store the name of the device in struct hidppBenjamin Tissoires
If a disconnect occurs while getting the actual name of the device (which can take several HID transactions), the name of the device will be the hid name, provided by the Unifying Receiver. This means that in some cases, the user space will see a different name that what it usually sees when there is no disconnect. We should store the name of the device in the struct hidpp. That way, if a disconnect occurs while we are accessing the name, hidpp_connect_event() can fail, and the input node is not created. The input node will be created only if we have a connection which lasts long enough to retrieve all the requested information: name, protocol, and specific configuration.

2015-01-06HID: input: fix confusion on conflicting mappingsDavid Herrmann
On an PC-101/103/104 keyboard (American layout) the 'Enter' key and its neighbours look like this: +---+ +---+ +-------+ | 1 | | 2 | | 5 | +---+ +---+ +-------+ +---+ +-----------+ | 3 | | 4 | +---+ +-----------+ On a PC-102/105 keyboard (European layout) it looks like this: +---+ +---+ +-------+ | 1 | | 2 | | | +---+ +---+ +-+ 4 | +---+ +---+ | | | 3 | | 5 | | | +---+ +---+ +-----+ (Note that the number of keys is the same, but key '5' is moved down and the shape of key '4' is changed. Keys '1' to '3' are exactly the same.) The keys 1-4 report the same scan-code in HID in both layouts, even though the keysym they produce is usually different depending on the XKB-keymap used by user-space. However, key '5' (US 'backslash'/'pipe') reports 0x31 for the upper layout and 0x32 for the lower layout, as defined by the HID spec. This is highly confusing as the linux-input API uses a single keycode for both. So far, this was never a problem as there never has been a keyboard with both of those keys present at the same time. It would have to look something like this: +---+ +---+ +-------+ | 1 | | 2 | | x31 | +---+ +---+ +-------+ +---+ +---+ +-----+ | 3 | |x32| | 4 | +---+ +---+ +-----+ HID can represent such a keyboard, but the linux-input API cannot. Furthermore, any user-space mapping would be confused by this and, luckily, no-one ever produced such hardware. Now, the HID input layer fixed this mess by mapping both 0x31 and 0x32 to the same keycode (KEY_BACKSLASH==0x2b). As only one of both physical keys is present on a hardware, this works just fine. Lets introduce hardware-vendors into this: ------------------------------------------ Unfortunately, it seems way to expensive to produce a different device for American and European layouts. Therefore, hardware-vendors put both keys, (0x31 and 0x32) on the same keyboard, but only one of them is hooked up to the physical button, the other one is 'dead'. This means, they can use the same hardware, with a different button-layout and automatically produce the correct HID events for American *and* European layouts. This is unproblematic for normal keyboards, as the 'dead' key will never report any KEY-DOWN events. But RollOver keyboards send the whole matrix on each key-event, allowing n-key roll-over mode. This means, we get a 0x31 and 0x32 event on each key-press. One of them will always be 0, the other reports the real state. As we map both to the same keycode, we will get spurious key-events, even though the real key-state never changed. The easiest way would be to blacklist 'dead' keys and never handle those. We could simply read the 'country' tag of USB devices and blacklist either key according to the layout. But... hardware vendors... want the same device for all countries and thus many of them set 'country' to 0 for all devices. Meh.. So we have to deal with this properly. As we cannot know which of the keys is 'dead', we either need a heuristic and track those keys, or we simply make use of our value-tracking for HID fields. We simply ignore HID events for absolute data if the data didn't change. As HID tracks events on the HID level, we haven't done the keycode translation, yet. Therefore, the 'dead' key is tracked independently of the real key, therefore, any events on it will be ignored. This patch simply discards any HID events for absolute data if it didn't change compared to the last report. We need to ignore relative and buffered-byte reports for obvious reasons. But those cannot be affected by this bug, so we're fine. Preferably, we'd do this filtering on the HID-core level. But this might break a lot of custom drivers, if they do not follow the HID specs. Therefore, we do this late in hid-input just before we inject it into the input layer (which does the exact same filtering, but on the keycode level). If this turns out to break some devices, we might have to limit filtering to EV_KEY events. But lets try to do the Right Thing first, and properly filter any absolute data that didn't change. This patch is tagged for 'stable' as it fixes a lot of n-key RollOver hardware. We might wanna wait with backporting for a while, before we know it doesn't break anything else, though.

2014-12-17HID: i2c-hid: Do not free buffers in i2c_hid_stop()Mika Westerberg
When a hid driver that uses i2c-hid as transport is unloaded, the hid core will call i2c_hid_stop() which releases all the buffers associated with the device. This includes also the command buffer. Now, when the i2c-hid driver itself is unloaded it tries to power down the device by sending it PWR_SLEEP command. Since the command buffer is already released we get following crash: [ 79.691459] BUG: unable to handle kernel NULL pointer dereference at (null) [ 79.691532] IP: [<ffffffffa05bc049>] __i2c_hid_command+0x49/0x310 [i2c_hid] ...

2014-12-17HID: rmi: Scan the report descriptor to determine if the device is suitable ↵Andrew Duggan
for the hid-rmi driver On composite HID devices there may be multiple HID devices on separate interfaces, but hid-rmi should only bind to the touchpad. The previous version simply checked that the interface protocol was set to mouse. Unfortuately, it is not always the case that the touchpad has the mouse interface protocol set. This patch takes a different approach and scans the report descriptor looking for the Generic Desktop Pointer usage and the Vendor Specific Top Level Collection needed by the hid-rmi driver to interface with the device.

2014-12-17HID: lenovo: Use native middle-button mode for compact keyboardsJamie Lentin
By default the middle button is in a compatibility mode, and generates standard wheel events when dragging with the middle trackpoint button. Unfortunately this is buggy: * The middle button comes up before starting wheel events, causing a middle click on whatever the mouse cursor was sitting on * The USB keyboard always generates the "native" horizontal wheel event, regardless of mode. Instead, enable the "native" mode the Windows driver uses, and add support for the custom events this generates. This fixes the USB keyboard wheel events, and the middle-click up event comes after the wheel events. Signed-off-by: Jamie Lentin <jm@lentin.co.uk> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2014-12-17HID: logitech-hidpp: separate HID++ from WTP processingPeter Wu
Previously wtp_raw_event would be called through hidpp_raw_hidpp_event (for the touchpad report) and hidpp_raw_event (for the mouse report). This patch removes one calling surface, making a clearer distinction between "generic HID++ processing" (matching internal reports) and device-specific event processing.
