2011-01-08HID: roccat: Add support for Roccat Kone[+] v2Stefan Achatz6-0/+1079
This patch adds support for Roccat Kone[+] gaming mouse. Kone[+] is an enhanced version of the old Kone with more memory for macros, a better sensor and more functionality.

2010-12-21USB: add support for Dream Cheeky DL100B Webmail Notifier (1d34:0004)Melchior FRANZ2-0/+3
So far the USBLED driver only supports Delcom's "USB Visual Signal Indicator" (http://www.delcomproducts.com/products_USBLMP.asp). The driver generates virtual files "red", "green", and "blue" under the device's /sys/ directory, where color values can be read from and written to. This patch adds support for Dream Cheeky's "DL100B Webmail Notifier" (http://www.dreamcheeky.com/webmail-notifier -- available from several shops, such as http://www.conrad.at/ce/de/product/777048/USB-WEBMAIL). This device isn't as pretty as Delcom's, but it's *far* cheaper, and its 3 LEDs can be set in 32 brightness steps each. The grey envelope contour can easily be removed, leaving a rather neutral white box (with a few small holes), which is useful for generic signalling purposes. Of course, the small circuit board can easily be put into a prettier case. The DL100B device pretends to be a HID, but the HID descriptor shows that it's not overly useful as such (see below). The patch therefore removes the "HID-ness" (hid-core.c, hid-ids.h), and adds the necessary commands to usbled.c. The protocol info comes from the developer's manual that Dream Cheeky kindly provided (815DeveloperManual.pdf).

2010-12-16hid: egalax: Convert to MT slotsHenrik Rydberg1-63/+23
The firmware in the joojoo reports touches sequentially, one per report, which confuses the current driver. A further complication is the absense of any indication of a touch frame. This patch converts the driver to the MT slots protocol, and outputs one full touch frame per report. This way, proper handling for both firmwares is ensured.

2010-12-16input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg1-28/+2
The drivers using the type B protocol all report tracking information the same way. The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver. This patch moves all tracking event handling over to the input core, simplifying both the existing drivers and the ones currently in preparation.

The device has 2 modes. The first one is an emulation of a touchscreen by sending left and right button, and the second mode is the one used in dual-touch (sending trackingID, touch and else). In case of a suspend/resume, the device switch back to the first mode described above (with left and right buttons).

2010-12-14HID: hid-mosart: ignore buttons reportBenjamin Tissoires1-0/+4
This commit allows the device to be recognized as a touchscreen, and not a touchpad by xf86-input-evdev. The device has 2 modes. The first one is an emulation of a touchscreen by sending left and right button, and the second mode is the one used in dual-touch (sending trackingID, touch and else). That's why there is a hid report containing left and right buttons (9000001 and 9000002). The point is that xorg relies on these fields to determine if it's a touchpad or a touchscreen. Clearing the report (return -1) makes xorg detecting it out of the box as a quite pleasant (dual)touchscreen.

2010-12-09HID: magicmouse: Don't report REL_{X,Y} for Magic TrackpadChase Douglas1-0/+5
With the recent switch to having the hid layer handle standard axis initialization, the Magic Trackpad now reports relative axes. This would be fine in the normal mode, but the driver puts the device in multitouch mode where no relative events are generated. Also, userspace software depends on accurate axis information for device type detection. Thus, ignoring the relative axes from the Magic Trackpad is best.

2010-12-07HID: Consolidate device existence checks in hiddev_ioctlValentine Barshak1-184/+103
Currently, if the device has been removed before hiddev_ioctl(), the -EIO is returned. If it's removed while hiddev_ioctl() is in progress, some commands are still processed fine, others return -ENODEV. This change takes the "existancelock" before processing ioctl commands and releases it at the end. If the device has been removed, always returns -ENODEV.

2010-12-07HID: Fix race between disconnect and hiddev_ioctlValentine Barshak1-37/+131
A USB HID device can be disconnected at any time. If this happens right before or while hiddev_ioctl is in progress, the hiddev_ioctl tries to access invalid hiddev->hid pointer. When the hid device is disconnected, the hiddev_disconnect() ends up with a call to hid_device_release() which frees hid_device, but doesn't set the hiddev->hid pointer to NULL. If the deallocated memory region has been re-used by the kernel, this can cause a crash or memory corruption. Since disconnect can happen at any time, we can't initialize struct hid_device *hid = hiddev->hid at the beginning of ioctl and then use it. This change checks hiddev->exist flag while holding the existancelock and uses hid_device only if it exists.
