2009-12-11USB: remove the auto_pm flagAlan Stern
This patch (as1302) removes the auto_pm flag from struct usb_device. The flag's only purpose was to distinguish between autosuspends and external suspends, but that information is now available in the pm_message_t argument passed to suspend methods.

2009-12-03HID: add multi-input quirk for NextWindow Touchscreen.Peter Hutterer
These touchscreens are mounted onto HP TouchSmart and the Dell Studio One 19. Without a quirk they report a wrong button set and the x/y coordinates through ABS_Z/ABS_RX, confusing the higher levels (most notably X.Org's evdev driver). Device id 0x003 covers models 1900, 2150, and 2700 [1] though testing could only be performed on a model 1900.

2009-11-05HID: fixup quirk for NCR devicesJiri Kosina
NCR devices are terminally broken by design -- they claim themselves to contain proper input applications in their HID report descriptor, but behave very badly if treated in standard way. According to NCR developers, the devices get confused when queried for reports in a standard way, rendering them unusable. NCR is shipping application called "RPSL" that can be used to drive these devices through hiddev, under the assumption that in-kernel driver doesn't perform initial report query. If it does, neither in-kernel nor hiddev-based driver can operate with these devices any more. Introduce a quirk that skips the report query for all NCR devices. The previous NOGET quirk was wrong and had been introduced because I misunderstood the nature of brokenness of these devices. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2009-08-20HID: support larger reports than 64 bytes in hiddevJiri Kosina
hiddev userspace driver uses a rignbuffer to store the parsed usages that should be returned through read(). This buffer is 64 bytes long, which is sufficient for queueing single USB 1.0 low-speed report, which is of maximum size 48 bytes. There are however USB HID devices which are full-speed USB devices, and therefore they are free to produce reports 64 bytes long. This is correctly handled by HID core, but read() on hiddev node gets stuck forever, because the ring buffer loops infinitely (as it is exactly 64 bytes long as well), never advancing the buffer pointer. Plus, the core driver is ready to handle highspeed devices, so we should be able to handle reports from such devices in the hiddev driver as well, which means we need larger ringbuffer.

2009-07-23HID: Support new variants of Samsung USB IR receiver (0419:0001)Robert Schedel
This patch extends the existing Samsung IrDA (0419:0001) quirk file with newly reported variants: * New device variants with 203 byte and 135 byte report descriptors were reported to be recognized incorrectly. This patch adds an autodetection for those two, using report descriptor size to enable new quirks. * Any other unknown 0419:0001 variants will now be treated without any quirk flags (i.e. IGNORE_HIDINPUT/HIDDEV_FORCE will not be set by default anymore). More details: 1. Descriptor size 184 bytes ("Satelco bundled remote") Already supported since kernel 2.6.25 (my old patch). 2. Descriptor size 203 bytes ("Optronix remote") This receiver mostly works with the regular HID input driver. Only when some keys are released, another spurious key press event is interpreted due to incorrect array ranges. According to HID 1.11, section 6.2.2.5, arrays should return a 0 value when no control is asserted, and ranges should go from 1 to the number of elements. The patch clips the value with a logical range from 1..15 (instead of originally 0..18). Ticket with more information available at https://bugs.launchpad.net/bugs/326986 3. Descriptor size 135 bytes ("Gotview remote") This receiver has a similar issue than the previous one, i.e. it mostly works with regular HID input, except some key press events get stuck on key release. The patch clips the array value from 1..14 (instead of originally 0..17). Ticket with more information available at http://bugs.archlinux.org/task/15216 4. Other unknown variants (found one report with 218 bytes, but no further information about issues) For such unknown variants we should refrain from changing any device flags. Currently, HIDINPUT is suppressed and HIDDEV is enforced (because in 2.6.25 the quirk table did not yet allow differentiating variants and we did not expect variants either). Now we should be as strict as possible and enable it only for the first variant above. Signed-off-by: Robert Schedel <r.schedel@yahoo.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2009-06-12HID: use debugfs for events/reports dumpingJiri Kosina
This is a followup patch to the one implemeting rdesc representation in debugfs rather than being dependent on compile-time CONFIG_HID_DEBUG setting. The API of the appropriate formatting functions is slightly modified -- if they are passed seq_file pointer, the one-shot output for 'rdesc' file mode is used, and therefore the message is formatted into the corresponding seq_file immediately. Otherwise the called function allocated a new buffer, formats the text into the buffer and returns the pointer to it, so that it can be queued into the ring-buffer of the processess blocked waiting on input on 'events' file in debugfs. 'debug' parameter to the 'hid' module is now used solely for the prupose of inetrnal driver state debugging (parser, transport, etc). Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2009-06-12HID: use debugfs for report dumping descriptorJiri Kosina
It is a little bit inconvenient for people who have some non-standard HID hardware (usually violating the HID specification) to have to recompile kernel with CONFIG_HID_DEBUG to be able to see kernel's perspective of the HID report descriptor and observe the parsed events. Plus the messages are then mixed up inconveniently with the rest of the dmesg stuff. This patch implements /sys/kernel/debug/hid/<device>/rdesc file, which represents the kernel's view of report descriptor (both the raw report descriptor data and parsed contents). With all the device-specific debug data being available through debugfs, there is no need for keeping CONFIG_HID_DEBUG, as the 'debug' parameter to the hid module will now only output only driver-specific debugging options, which has absolutely minimal memory footprint, just a few error messages and one global flag (hid_debug). We use the current set of output formatting functions. The ones that need to be used both for one-shot rdesc seq_file and also for continuous flow of data (individual reports, as being sent by the device) distinguish according to the passed seq_file parameter, and if it is NULL, it still output to kernel ringbuffer, otherwise the corresponding seq_file is used for output. The format of the output is preserved. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
