| * HID: handle cases of volume knobs generating relative valuesJiri Kosina2007-07-091-0/+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>

| * HID: support for logitech cordless desktop LX500 special mappingRyo Dairiki2007-07-092-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (This mouse has only 4 buttons and 2D wheel. There is no such buttons like 11 and 12.) Signed-off-by: Jiri Kosina <jkosina@suse.cz>
| * HID: fix autocentering of PID devicesDiogo Kastrup2007-07-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | When setting the autocentering of PID devices, PID_DIRECTION_ENABLE is not being explicitely set to 1. This results in autocentering working only on the vertical axis when this field is preset to 0. Fix that by setting it explicitely to 1 when preparing the set_effect report for autocentering spring effect.

| * HID: separate quirks for report descriptor fixupJiri Kosina2007-07-092-91/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lately there have been quite a lot of bug reports against broken devices which require us to fix their report descriptor in the runtime, before it is passed to the HID parser. Those devices have eaten quite an amount of our quirks space, which isn't particularly necessary - the quirks are not needed after the report descriptor is parsed, and they just consume bits. Therefore this patch separates the quirks for report descriptor fixup, and moves their handling into separate code. The quirks are then forgotten as soon as the report descriptor has been parsed. Module parameter 'rdesc_quirks' is introduced to be able to modify these quirks in runtime in a similar way to 'quirks' parameter for ordinary HID quirks. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| * HID: support for Petalynx Maxter remote controlJiri Kosina2007-07-093-2/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Petalynx Maxter remote control [1] 0x18b1/0x0037 emits 0xfa and 0xfc from consumer page (reserved in HUT 1.12) for back and more keys. 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.

| * HID: fix mismatch between hid-input HUT find/search mapping and the HUTHans de Goede2007-07-091-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When comparing usb vs ps2 / testing the keycodes generated for the easy access keys on my trust (microsoft compatible) keyboard. I noticed the search key generated the keycode for find when connected through USB. This lead me to check the consumer page mappings in hid-input.c . And it turns out the the mapping for ID 0x221 deviates from the HUT standard document: http://www.usb.org/developers/devclass_docs/Hut1_12.pdf Currently it is incorrectly mapped to find, whereas it should be mapped to search. I also added missing bindings for ID 0x21f, the real find and for 0x222, goto. Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| * HID: force hid-input for Microsoft SideWinder GameVoice deviceJiri Kosina2007-07-092-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This patch establishes a new quirk which forces hid-input to claim a device it will otherwise leave untouched.

* USB HID: report descriptor of Cypress USB barcode readers needs fixupJiri Kosina2007-05-092-0/+32
| | | | | | | | | | | | | | Certain versions of Cypress USB barcode readers (this problem is known to happen at least with PIDs 0xde61 and 0xde64) have report descriptor which has swapped usage min and usage max tag. This results in HID parser failing for report descriptor of these devices, as it (wrongly) requires allocating more usages than HID_MAX_USAGES. Solve this by walking through the report descriptor for such devices, and swap the usage min and usage max items (and their values) to be in proper order.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some HID devices are looking on the unused bits in the HID reports they receive. This is violating the specification, but we want to make those devices work. Well-behaving devices are unaffected, as they don't care about the unused bits. If bitsused % 8 is 0 all bits in data[] get used and we don't need to clear anything. Otherwise (bitsused % 8) bits of the last byte get used. By shifting 1 for (bitsused % 8) bits and subtracting 1 we create a mask consisting of (bitsused % 8) ones and remaining zeroes. By ANDing we clear the upper unused bits.

As a result, the very next error would trigger an immediate reset, even if it was a chance event occurring long after the previous error. More USB keyboards and mice than one might expect end up getting I/O errors. Almost always this results from hardware problems of one sort of another. For example, people attach the device to a USB extension cable, which degrades the signal. Or they simply have poor quality cables to begin with. Or they use a KVM switch which doesn't handle USB messages correctly. Etc... There have been reports from several users in which these I/O errors would occur more or less randomly, at intervals ranging from seconds to minutes. The error-handling code in hid-core.c was originally meant for situations where a single outage would persist for a few hundred ms (electromagnetic interference, for example). It didn't work right when these more sporadic errors occurred, because of a flaw in the logic which this patch fixes. This patch (as873) fixes that oversight.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes bogus zeroing of unused bits in output reports, introduced in Simon's patch in commit d4ae650a. According to the specification, any sane device should not care about values of unused bits. What is worse, the zeroing is done in a way which is broken and might clear certain bits in output reports which are actually _used_ - a device that has multiple fields with one value of the size 1 bit each might serve as an example of why this is bogus - the second call of hid_output_report() would clear the first bit of report, which has already been set up previously. This patch will break LEDs on SpaceNavigator, because this device is broken and takes into account the bits which it shouldn't touch. The quirk for this particular device will be provided in a separate patch. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
