2015-10-05HID: usbhid: Fix for the WiiU adapter from MayflashOliver Schmitt1-0/+1
The WiiU adapter from Mayflash (see http://www.mayflash.com/Products/NINTENDOWiiU/W009.html) is not working correctly. The "XInput" mode works fine, the controller is recognized as a xbox controller. But it is only possible to connect one controller with this method. In "DInput" mode the device is recognized as some kind of mouse input but no joystick is created. This commit will change this behavior with HID_QUIRK_MULTI_INPUT to split the device into 4 input devices so that it will also create joysticks in /dev/input/js*.

2015-08-19HID: usbhid: Fix the check for HID_RESET_PENDING in hid_io_errorDon Zickus1-1/+1
It was reported that after 10-20 reboots, a usb keyboard plugged into a docking station would not work unless it was replugged in. Using usbmon, it turns out the interrupt URBs were streaming with callback errors of -71 for some reason. The hid-core.c::hid_io_error was supposed to retry and then reset, but the reset wasn't really happening. The check for HID_NO_BANDWIDTH was inverted. Fix was simple. Tested by reporter and locally by me by unplugging a keyboard halfway until I could recreate a stream of errors but no disconnect.

2015-03-16HID: pidff: support more than one concurrent effectJim Keir1-0/+6
The PID driver (usbhid/hid-pidff.c) does not set the effect ID when uploading an effect. The result is that the initial upload works but subsequent uploads to modify effect parameters are all directed at the last-created effect. The targeted effect ID must be passed back to the device when effect parameters are changed. This is done at the start of "pidff_set_condition_report", "pidff_set_periodic_report" etc. based on the value of "pidff->block_load[PID_EFFECT_ BLOCK_INDEX].value[0]". This value is only ever set during pidff_request_effect_upload. The result is stored in "pidff->pid_id[effect->id]" at the end of pid_upload_effect, for later use. However, if an effect is modified and re-sent then this identifier is not being copied back from pidff->pid_id[effect->id] before sending the command to the device. The fix is to do this at the start of pidff_upload_effect. Signed-off-by: Jim Keir <jimkeir@oracledbadirect.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2015-03-03HID: uclogic: Set quirks from inside the driverBenjamin Tissoires1-4/+0
Based on a patch from: Nikolai Kondrashov <Nikolai.Kondrashov@redhat.com> Most of the tablets handled by hid-uclogic already use MULTI_INPUT. For the ones which are not quirked in usbhid/hidquirks, they have a custom report descriptor which contains only one report per HID interface. For those tablets HID_QUIRK_MULTI_INPUT is transparent. According to https://github.com/DIGImend/tablets, the only problematic tablet currently handled by hid-uclogic is the TWHA60 v3. This tablet presents different report descriptors from the ones currently quirked. This is not a problem per se, given that this tablet is not supported currently in this version (it needs the same command as a Huion to start forwarding events).

2015-01-26HID: pidff: Fix initialisation forMicrosoft Sidewinder FF Pro 2Jim Keir1-0/+6
The FF2 driver (usbhid/hid-pidff.c) sends commands to the stick during ff_init. However, this is called inside a block where driver_input_lock is locked, so the results of these initial commands are discarded. This behavior is the "killer", without this nothing else works. ff_init issues commands using "hid_hw_request". This eventually goes to hid_input_report, which returns -EBUSY because driver_input_lock is locked. The change is to delay the ff_init call in hid-core.c until after this lock has been released. Calling hid_device_io_start() releases the lock so the device can be configured. We also need to call hid_device_io_stop() on exit for the lock to remain locked while ending the init of the drivers.

2014-10-29HID: usbhid: prevent unwanted events to be sent when re-opening the deviceBenjamin Tissoires2-12/+25
When events occurs while no one is listening to the node (hid->open == 0 and usb_kill_urb() called) some events are still stacked somewhere in the USB (kernel or device?) stack. When the node gets reopened, these events are drained, and this results in spurious touch down/up, or mouse button clicks. The problem was spotted with touchscreens in fdo bug #81781 [1], but it actually occurs with any mouse using hid-generic or touchscreen. A way to reproduce it is to call: $ xinput disable 9 ; sleep 5 ; xinput enable 9 With 9 being the device ID for the touchscreen/mouse. During the "sleep", produce some touch events or click events. When "xinput enable" is called, at least one click is generated. This patch tries to fix this by draining the queue for 50 msec and during this time frame, not forwarding these old events to the hid layer. Hans completed the explanation: """ Devices like mice (basically any hid device) will have a fifo on the device side, when we stop submitting urbs to get hid reports from it, that fifo will fill up, and when we resume we will get whatever is there in that fifo.

2014-09-04HID: usbhid: improve handling of Clear-Halt and resetAlan Stern1-25/+9
This patch changes the way usbhid carries out Clear-Halt and reset. Currently, after a Clear-Halt on the interrupt-IN endpoint, the driver immediately restarts the interrupt URB, even if the Clear-Halt failed. This doesn't work out well when the reason for the failure was that the device was disconnected (when a low- or full-speed device is connected through a hub to an EHCI controller, transfer errors caused by disconnection are reported as stalls by the hub). Instead now the driver will attempt a reset after a failed Clear-Halt. The way resets are carried out is also changed. Now the driver will call usb_queue_reset_device() instead of calling usb_reset_device() directly. This avoids a deadlock that would arise when a device is unplugged: The hid_reset() routine runs as a workqueue item, a reset attempt after the device has been unplugged will fail, failure will cause usbhid to be unbound, and the disconnect routine will try to do cancel_work_sync(). The usb_queue_reset_device() implementation is carefully written to handle scenarios like this one properly.

Set disconnected flag in struct usbhid when a usb device is removed. Check for disconnected flag before sending urb requests. This prevents a kernel panic when a hid driver calls hid_hw_request() after removing a usb device.
