* HID: add battery quirk for USB_DEVICE_ID_APPLE_ALU_WIRELESS_2011_ISO keyboardKarl Relton2014-12-171-0/+3
| | | | | | | | | | Apple bluetooth wireless keyboard (sold in UK) has always reported zero for battery strength no matter what condition the batteries are actually in. With this patch applied (applying same quirk as other Apple keyboards), the battery strength is now correctly reported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit which introduced TransducerSerialNumber (368c966) is missing two crucial implementation details. Firstly, the commit does not set the type/code/bit/max fields as expected later down the code which can cause the driver to crash when a tablet with this usage is connected. Secondly, the call to 'set_bit' causes MSC_PULSELED to be sent instead of the expected MSC_SERIAL. This commit addreses both issues.

| | | | | | | | | | | | | | | Atmel 840B digitizer presents a stylus interface which reports twice the X coordinate and then twice the Y coordinate. In its current implementation, hid-input assign the first X to X, then the second to Y, then the first Y to Z, then the second one to RX. This is wrong, and X should always be mapped to X, no matter what. A solution consists in forcing X, Y, Z, RX, RY, RZ to be mapped to their correct user space counter part.

* HID: Fix unit exponent parsing againNikolai Kondrashov2013-10-181-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert some changes done in 774638386826621c984ab6994439f474709cac5e. Revert all changes done in hidinput_calc_abs_res as it mistakingly used "Unit" item exponent nibbles to affect resolution value. This wasn't breaking resolution calculation of relevant axes of any existing devices, though, as they have only one dimension to their units and thus 1 in the corresponding nible. Revert to reading "Unit Exponent" item value as a signed integer in hid_parser_global to fix reading specification-complying values. This fixes resolution calculation of devices complying to the HID standard, including Huion, KYE, Waltop and UC-Logic graphics tablets which have their report descriptors fixed by the drivers. Explanations follow. There are two "unit exponents" in HID specification and it is important not to mix them. One is the global "Unit Exponent" item and another is nibble values in the global "Unit" item. See 6.2.2.7 Global Items. The "Unit Exponent" value is just a signed integer and is used to scale the integer resolution unit values, so fractions can be expressed. The nibbles of "Unit" value are used to select the unit system (nibble 0), and presence of a particular basic unit type in the unit formula and its *exponent* (or power, nibbles 1-6). And yes, the latter is in two complement and zero means absence of the unit type. Taking the representation example of (integer) joules from the specification: [mass(grams)][length(centimeters)^2][time(seconds)^-2] * 10^-7 the "Unit Exponent" would be -7 (or 0xF9, if stored as a byte) and the "Unit" value would be 0xE121, signifying: Nibble Part Value Meaning ----- ---- ----- ------- 0 System 1 SI Linear 1 Length 2 Centimeters^2 2 Mass 1 Grams 3 Time -2 Seconds^-2 To give the resolution in e.g. hundredth of joules the "Unit Exponent" item value should have been -9. See also the examples of "Unit" values for some common units in the same chapter. However, there is a common misunderstanding about the "Unit Exponent" value encoding, where it is assumed to be stored the same as nibbles in "Unit" item. This is most likely due to the specification being a bit vague and overloading the term "unit exponent". This also was and still is proliferated by the official "HID Descriptor Tool", which makes this mistake and stores "Unit Exponent" as such. This format is also mentioned in books such as "USB Complete" and in Microsoft's hardware design guides. As a result many devices currently on the market use this encoding and so the driver should support them.

| * HID: input: generic hidinput_input_event handlerDavid Herrmann2013-07-311-1/+79
|/ | | | | | | | | | | | | | | | | | | | | The hidinput_input_event() callback converts input events written from userspace into HID reports and sends them to the device. We currently implement this in every HID transport driver, even though most of them do the same. This provides a generic hidinput_input_event() implementation which is mostly copied from usbhid. It uses a delayed worker to allow multiple LED events to be collected into a single output event. We use the custom ->request() transport driver callback to allow drivers to adjust the outgoing report and handle the request asynchronously. If no custom ->request() callback is available, we fall back to the generic raw output report handler (which is synchronous). Drivers can still provide custom hidinput_input_event() handlers (see logitech-dj) if the generic implementation doesn't fit their needs.

* | HID: input: return ENODATA if reading battery attrs failsDavid Herrmann2013-05-291-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | power_supply core has the bad habit of calling our battery callbacks from within power_supply_register(). Furthermore, if the callbacks fail with an unhandled error code, it will skip any uevent that it might currently process. So if HID-core registers battery devices, an "add" uevent is generated and the battery callbacks are called. These will gracefully fail due to timeouts as they might still hold locks on event processing. One could argue that this should be fixed in power_supply core, but the least we can do is to signal ENODATA so power_supply core will just skip the property and continue with the uevent. This fixes a bug where "add" and "remove" uevents are skipped for battery devices. upower is unable to track these devices and currently needs to ignore them. This patch also overwrites any other error code. I cannot see any reason why we should forward protocol- or I/O-errors to the power_supply core. We handle these errors in hid_ll_driver later, anyway, so just skip them. power_supply core cannot do anything useful with them, anyway, and we avoid skipping important uevents and confusing user-space. Thanks a lot to Daniel Nicoletti for pushing and investigating on this.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Button names for USB gamepads are currently assigned incorrectly, as the evdev code assigned to buttons is "BTN_GAMEPAD + code", which on devices with more then 16 buttons bleeds over into button names reserved for graphic tablets (BTN_TOOL_PEN, etc.). This causes problems further down the line as the device are now no longer detected as joystick. This patch fixes that by assigning buttons outside the range to BTN_TRIGGER_HAPPY (as is already the case for USB joysticks). Furthermore this patch corrects the assignment to BTN_TRIGGER_HAPPY, as currently the first button over 16 is assigned to BTN_TRIGGER_HAPPY17 (i.e. BTN_TRIGGER_HAPPY+0x10) not BTN_TRIGGER_HAPPY.

|/ | | | | | | | | | | | | | | | | | | Switch the driver over to device group handling. By adding the HID_GROUP_MULTITOUCH group to hid-core, hid-generic will no longer match multitouch devices. By adding the HID_GROUP_MULTITOUCH entry to the device list, hid-multitouch will match all unknown multitouch devices, and udev will automatically load the module. Since HID_QUIRK_MULTITOUCH never gets set, the special quirks handling can be removed. Since all HID MT devices have HID_DG_CONTACTID, they can be removed from the hid_have_special_driver list. With this patch, the unknown device ids are no longer NULL, so the code is modified to check for the generic entry instead.

* | HID: hid-input: allow array fields out of rangeNikolai Kondrashov2012-03-051-2/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow array field values out of range as per HID 1.11 specification, section 6.2.25: Rather than returning a single bit for each button in the group, an array returns an index in each field that corresponds to the pressed button (like keyboard scan codes). An out-of range value in and array field is considered no controls asserted. Apparently, "and" above is a typo and should be "an". This fixes at least Waltop tablet pen clicks - otherwise BTN_TOUCH is never released. The relevant part of Waltop tablet report descriptors is this: 0x09, 0x42, /* Usage (Tip Switch), */ 0x09, 0x44, /* Usage (Barrel Switch), */ 0x09, 0x46, /* Usage (Tablet Pick), */ 0x15, 0x01, /* Logical Minimum (1), */ 0x25, 0x03, /* Logical Maximum (3), */ 0x75, 0x04, /* Report Size (4), */ 0x95, 0x01, /* Report Count (1), */ 0x80, /* Input, */ This is a regression fix for commit b4b583d ("HID: be more strict when ignoring out-of-range fields").
