2012-10-02HID: Fix logitech-dj: missing Unifying device issueNestor Lopez Casado
commit 596264082f10dd4a567c43d4526b2f54ac5520bc upstream. This patch fixes an issue introduced after commit 4ea5454203d991ec ("HID: Fix race condition between driver core and ll-driver"). After that commit, hid-core discards any incoming packet that arrives while hid driver's probe function is being executed. This broke the enumeration process of hid-logitech-dj, that must receive control packets in-band with the mouse and keyboard packets. Discarding mouse or keyboard data at the very begining is usually fine, but it is not the case for control packets. This patch forces a re-enumeration of the paired devices when a packet arrives that comes from an unknown device. Based on a patch originally written by Benjamin Tissoires.

2012-08-09HID: hid-multitouch: fix input mode feature commandBenjamin Tissoires
commit 4aceed37e315e8eaa26cb4c8dfd619a32fa24669 upstream. Zytronic panels shows a new way of setting the Input Mode feature. This feature is put in the second usage in the HID feature, instead of the first, as the majority of the multitouch devices. This patch adds a detection step when the feature is presented to know where the feature is located in the report. We can then trigger the right command to the device. This removes the magic number "0" in the function mt_set_input_mode.

2012-05-11HID: logitech: read all 32 bits of report type bitfieldJonathan Nieder
On big-endian systems (e.g., Apple PowerBook), trying to use a logitech wireless mouse with the Logitech Unifying Receiver does not work with v3.2 and later kernels. The device doesn't show up in /dev/input. Older kernels work fine. That is because the new hid-logitech-dj driver claims the device. The device arrival notification appears: 20 00 41 02 00 00 00 00 00 00 00 00 00 00 00 and we read the report_types bitfield (02 00 00 00) to find out what kind of device it is. Unfortunately the driver only reads the first 8 bits and treats that value as a 32-bit little-endian number, so on a powerpc the report type seems to be 0x02000000 and is not recognized. Even on little-endian machines, connecting a media center remote control (report type 00 01 00 00) with this driver loaded would presumably fail for the same reason. Fix both problems by using get_unaligned_le32() to read all four bytes, which is a little clearer anyway. After this change, the wireless mouse works on Hugo's PowerBook again.

All known hid-multitouch devices currently match any device group.

This patch narrows the MT device list to match only HID_GROUP_MULTITOUCH, which solves the problem.

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.

2012-05-01HID: Scan the device for group info before adding itHenrik Rydberg
In order to allow the report descriptor to influence the hid device properties, one needs to parse the descriptor early, without reference to any driver. Scan the descriptor for group information during device add, before the device has been broadcast to userland. The device modalias will contain group information which can be used to differentiate between modules. For starters, just handle the generic group.

2012-05-01HID: Add device group to modaliasHenrik Rydberg
HID devices are only partially presented to userland. Hotplugged devices emit events containing a modalias based on the basic bus, vendor and product entities. However, in practise a hid device can depend on details such as a single usb interface or a particular item in a report descriptor. This patch adds a device group to the hid device id, and broadcasts it using uevent and the device modalias. The module alias generation is modified to match. As a consequence, a device with a non-zero group will be processed by the corresponding group driver instead of by the generic hid driver.
