2009-06-10HID: fix inverted wheel for bluetooth version of apple mighty mouseJiri Kosina
Bluetooth version of Apple Mighty mouse (0x05ac/0x030c) doesn't, according to multiple reports on linux-input@, need the same quirk as the USB version of this mouse (0x05ac/0x0304) does. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2009-05-20HID: Multitouch support for the N-Trig touchscreenStephane Chatty
Adds support for multitouch interaction on the N-Trig touchscreen, using the new ABS_MT_* input constants. Single touch support works as previously. This code was tested against two versions of the N- Trig firmware: one that supports dual pen/finger single touch, and one that supports finger multitouch but no pen at all. Copyright notices that looked wrong were removed, as it seems that there is only code written in 2009 by Rafin Rubin and Stephane Chatty in this file.

2009-05-20HID: add new multitouch and digitizer contantsStephane Chatty
Added constants to hid.h for all digitizer usages (including the new multitouch ones that are not yet in the official USB spec but are being pushed by Microsft as described in their paper "Digitizer Drivers for Windows Touch and Pen-Based Computers"). Updated hid-debug.c to support the new MT input constants such as ABS_MT_POSITION_X. Signed-off-by: Stephane Chatty <chatty@enac.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2009-05-15HID: fix hid-ff drivers so that devices work even without ff supportJiri Kosina
Currently, the hid-*ff force feedback drivers, which claim the blacklisted device on a HID bus, are only compiled in if the user selects force feedback support. However we want the device to be supported even when the kernel is configured without force feedback. This patch fixes the drivers in a way that they get compiled even if force feedback is turned off; all the force feedback support code is compiled out in such case, and the driver works as a usual driver on HID bus, claiming and initializing the device, making it operational without FF effects.

2009-05-15HID: force feedback support for SmartJoy PLUS PS2/USB adapterJussi Kivilinna
This driver adds force feedback support for SmartJoy PLUS PS2/USB adapter. I made this driver one device spesific instead of making generic 'wisegroup-ff' because I have another Wisegroup PS2/USB adapter that doesn't work same way as SmartJoy PLUS. If another device that is compatible pops up, this driver could be then renamed to something more generic.

Based on the work by Andrew Zabolotny, an HID driver for the Bluetooth Wacom tablet. This is required as it uses a slightly different protocols from what's currently support by the drivers/input/wacom* driver, and those only support USB.

Some months ago I send patch which adds autocentering for Logitech MOMO Wheel. Now I have access to Logitech G25 Racing Wheel and test autocentering for it. I write patch for current kernel to support autocentering for G25 in legacy mode (this device supports other modes, but after switching device reconnects with ID 0xc299 and FF support comes out) and others Logitech (Driving Force, Formula Force Ex etc) wheels with ID 046d:c294.

If the device is not claimed by hid-input (i.e devices driver by userspace hiddev/hidraw-based drivers, or completely detached from HID and driver by libusb), we must not check the hid->inptus, as it is not guaranteed to be initialized, as this is performed only for devices handled by hid-input.

2009-03-30HID: fix race between usb_register_dev() and hiddev_open()Oliver Neukum
upon further thought this code is still racy. retval = usb_register_dev(usbhid->intf, &hiddev_class); here you open a window during which open can happen if (retval) { err_hid("Not able to get a minor for this device."); hid->hiddev = NULL; kfree(hiddev); return -1; } else { hid->minor = usbhid->intf->minor; hiddev_table[usbhid->intf->minor - HIDDEV_MINOR_BASE] = hiddev; and will fail because hiddev_table hasn't been updated The obvious fix of using a mutex to guard hiddev_table doesn't work because usb_open() and usb_register_dev() take minor_rwsem and we'd have an AB-BA deadlock. We need a lock usb_open() also takes in the right order and that leaves only one option, BKL. I don't like it but I see no alternative. Once the usb_open() implements something better than lock_kernel(), we could also do so. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2009-03-30HID: bring back possibility to specify vid/pid ignore on module loadJiri Kosina

2009-03-25HID: autosuspend support for USB HIDOliver Neukum
This uses the USB busy mechanism for aggessive autosuspend of USB HID devices. It autosuspends all opened devices supporting remote wakeup after a timeout unless - output is being done to the device - a key is being held down (remote wakeup isn't triggered upon key release) - LED(s) are lit - hiddev is opened As in the current driver closed devices will be autosuspended even if they don't support remote wakeup. The patch is quite large because output to devices is done in hard interrupt context meaning a lot a queuing and locking had to be touched. The LED stuff has been solved by means of a simple counter. Additions to the generic HID code could be avoided. In addition it now covers hidraw. It contains an embryonic version of an API to let the generic HID code tell the lower levels which capabilities with respect to power management are needed.

2009-03-16Rationalize fasync return valuesJonathan Corbet
Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

2009-03-10HID: fix waitqueue usage in hiddevJohannes Weiner
DECLARE_WAITQUEUE doesn't initialize the wait descriptor's task_list to 'empty' but to zero. prepare_to_wait() will not enqueue the descriptor to the waitqueue and finish_wait() will do list_del_init() on a list head that contains NULL pointers, which oopses. This was introduced by 079034073 "HID: hiddev cleanup -- handle all error conditions properly". The prior code used an unconditional add_to_waitqueue() which didn't care about the wait descriptor's list head and enqueued the thing unconditionally. The new code uses prepare_to_wait() which DOES check the prior list state, so use DEFINE_WAIT instead.
