2016-04-05HID: wacom: Support switching from vendor-defined device mode on G9 and G11Jason Gerecke
A tablet PC booted into Windows may have its pen/touch hardware switched into "Wacom mode" similar to what we do with explicitly-supported hardware. Some devices appear to maintain this state across reboots, preventing their use with the generic HID driver. This patch adds support for detecting the presence of the mode switch feature report used by devices based on the G9 and G11 chips and has the HID codepath always attempt to reset the device back to sending standard HID reports.

Looks like recent changes in the Wacom driver made the Bamboo ONE crashes. The tablet behaves as if it was a regular Bamboo device with pen, touch and pad, but there is no physical pad connected to it. The weird part is that the pad is still sending events and given that there is no input node connected to it, we get anull pointer exception.

2016-03-24HID: usbhid: fix inconsistent reset/resume/reset-resume behaviorAlan Stern
The usbhid driver has inconsistently duplicated code in its post-reset, resume, and reset-resume pathways. reset-resume doesn't check HID_STARTED before trying to restart the I/O queues. resume fails to clear the HID_SUSPENDED flag if HID_STARTED isn't set. resume calls usbhid_restart_queues() with usbhid->lock held and the others call it without holding the lock. The first item in particular causes a problem following a reset-resume if the driver hasn't started up its I/O. URB submission fails because usbhid->urbin is NULL, and this triggers an unending reset-retry loop. This patch fixes the problem by creating a new subroutine, hid_restart_io(), to carry out all the common activities. It also adds some checks that were missing in the original code: After a reset, there's no need to clear any halted endpoints. After a resume, if a reset is pending there's no need to restart any I/O until the reset is finished. After a resume, if the interrupt-IN endpoint is halted there's no need to submit the input URB until the halt has been cleared.

The wiimote motion plus gyros use two scales to report fast and slow rotation - below 440 deg/s uses 8192/440 units / deg/s, and above uses 8192/2000 units / deg/s. Previously this driver attempted to linearize the two by scaling the fast rate by 18 and the slow by 9, but this results in a scale of 8192*9/440 = ~167.564 for slow and 8192*18/2000 = 73.728 for fast.

2016-03-10HID: i2c-hid: Fix suspend/resume when already runtime suspendedDoug Anderson
On ACPI-based systems ACPI power domain code runtime resumes device before calling suspend method, which ensures that i2c-hid suspend code starts with device not in low-power state and with interrupts enabled. On other systems, especially if device is not a part of any power domain, we may end up calling driver's system-level suspend routine while the device is runtime-suspended (with controller in presumably low power state and interrupts disabled). This will result in interrupts being essentially disabled twice, and we will only re-enable them after both system resume and runtime resume methods complete. Unfortunately i2c_hid_resume() calls i2c_hid_hwreset() and that only works properly if interrupts are enabled. Also if device is runtime-suspended driver's suspend code may fail if it tries to issue I/O requests. Let's fix it by runtime-resuming the device if we need to run HID driver's suspend code and also disabling interrupts only if device is not already runtime-suspended. Also on resume we mark the device as running at full power (since that is what resetting will do to it).

2016-01-28HID: logitech-hidpp: Force feedback support for the Logitech G920Edwin Velds
This patch implements force feedback support for the Logitech G920 Driving Force Racing Wheel. It is a generic implementation of feature 0x8123 of the Logitech HID++ protocol and should be usable for any future devices that implement this feature. This patch should be applied after the basic G920 support patch by Simon Wood: http://www.spinics.net/lists/linux-input/msg42174.html The driving supports everything that is supported by the G920 firmware: FF_CONSTANT FF_PERIODIC FF_SINE FF_SQUARE FF_SAW_UP FF_SAW_DOWN FF_TRIANGLE FF_SPRING FF_DAMPER FF_AUTOCENTER FF_GAIN and for version 2 firmware also: FF_FRICTION FF_INERTIA FF_RAMP Both envelopes and replay values are supported as well, but some problems may occur when using firmware release 1. There is also a small residual clockwise damper in the wheel when using the first firmware release. All problems are fixed in the soon te be released firmware version 2. The default spring is disabled by permanently placing a spring force in the wheel. This spring is also used as the autocenter spring. Note: The wheel _DOES_NOT_ auto switch to Logitech/HID mode (it is stuck in XBox since the xpad changes where not included). Michal has an alternative approach documented here (and the changes should be submitted upstream to usb_modeswitch project): === Create a file named "046d:c261" in "/etc/usb_modeswitch.d" with the following content: DefaultVendor=046d DefaultProduct=c261 MessageEndpoint=01 ResponseEndpoint=01 TargetClass=0x03 MessageContent="0f00010142" Then run "usb_modeswitch -c /etc/modeswitch.d/046d:c291" as root and watch the magic happen:) === [jkosina@suse.cz: added information about mode switching from Simon] [jkosina@suse.cz: fixed a few stylistic issues pointed out by Simon] [jkosina@suse.cz: fix merge conflict due to to_hid_device() changes] Signed-off-by: Edwin Velds <e.velds@gmail.com> Tested-by: Elias Vanderstuyft <elias.vds@gmail.com> Tested-by: Simon Wood <simon@mungewell.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2016-01-27HID: rmi: Check that the device is a RMI device in suspend and resume callbacksAndrew Duggan
Commit 092563604217 ("HID: rmi: Disable scanning if the device is not a wake source") introduced a regression for devices which use hid-rmi to handle composite USB devices. The suspend or resume callbacks are not checking that the device is a RMI device before calling rmi_read or rmi_write. This results in dereferencing uninitialized variables on non RMI devices. This patch checks that the RMI_DEVICE flag is set before sending RMI commands to the device.
