2013-01-17HID: Support Jess/Saitek Color Rumble PadMichael Karcher
Add support for another gamepad to the hid-pl driver. The "color rumble pad P580" marketed using the "Saitek" brand in Germany, and using a USB Vendor ID attributed to "Jess" seems to be electronically identical to the 4-field variant of the "Green Asia" gamepad. The pad has been tested to support rumble strengths up to 255, not just 127. Signed-off-by: Michael Karcher <kernel@mkarcher.dialup.fu-berlin.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-01-15HID: add support for Sony RF receiver with USB product id 0x0374Fernando Luis Vázquez Cao
Some Vaio desktop computers, among them the VGC-LN51JGB multimedia PC, have a RF receiver, multi-interface USB device 054c:0374, that is used to connect a wireless keyboard and a wireless mouse. The keyboard works flawlessly, but the mouse (VGP-WMS3 in my case) does not seem to be generating any pointer events. The problem is that the mouse pointer is wrongly declared as a constant non-data variable in the report descriptor (see lsusb and usbhid-dump output below), with the consequence that it is ignored by the HID code. Add this device to the have-special-driver list and fix up the report descriptor in the Sony-specific driver which happens to already have a fixup for a similar firmware bug. # lsusb -vd 054C:0374 Bus 003 Device 002: ID 054c:0374 Sony Corp.

2013-01-03Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2013-01-03HID: hid-sony: fix troubles with Sony remote clonesMauro Carvalho Chehab
There are some Sony clone gamepads that are incompatible with PS3 since firmware 3.50, as they decided to prevent those devices to work, without any good technical reason. I was one of those 'blessed' people affected by their niceness with their customers. Marcelo also has another device with a similar problem. Perhaps due to Sony's way to block the device, damaging the device's eeprom, or perhaps because they just have a different, broken Report descriptor, there are 3 buttons that don't work on both devices (the ones equivalent to square, round and X). What it happens is that the descriptor generate weird EV_ABS events to those buttons, instead of EV_MSC/EV_KEY. A fix that seems to be enough for them is to return the original sixaxis table instead of the broken one. That's what this patch does. Yet, there are some missing entries at the used keytable. On my tests, all keys are now producing the right events, but the reported keycodes look weird: "square" key: (Button.0010 = 1) 1355524363.460835: event type EV_MSC(0x04): scancode = 0x90010 1355524363.460835: event type EV_KEY(0x01) key_up: BTN_DEAD(0x0001) "round" key: (Button.000e = 1) 1355524410.908705: event type EV_MSC(0x04): scancode = 0x9000e 1355524410.908705: event type EV_KEY(0x01) key_down: (0x0001) 1355524410.971788: event type EV_MSC(0x04): scancode = 0x9000e 1355524410.971788: event type EV_KEY(0x01) key_up: (0x0001) "X" key: (Button.000f = 1) 1355524384.880813: event type EV_MSC(0x04): scancode = 0x9000f 1355524384.880813: event type EV_KEY(0x01) key_down: (0x0001) 1355524384.979815: event type EV_MSC(0x04): scancode = 0x9000f 1355524384.979815: event type EV_KEY(0x01) key_up: (0x0001) The rationale is likely due to those entries at rdesc table, where the Kernel were not likely able to parse: Button.000d ---> Key.? Button.000e ---> Key.? Button.000f ---> Key.? Button.0010 ---> Key.BtnDead Button.0011 ---> Key.? Button.0012 ---> Key.? Button.0013 ---> Key.?

2012-12-07HID: hidp: fallback to input session properly if hid is blacklistedLamarque V. Souza
This patch against kernel 3.7.0-rc8 fixes a kernel oops when turning on the bluetooth mouse with id 0458:0058 [1]. The mouse in question supports both input and hid sessions, however it is blacklisted in drivers/hid/hid-core.c so the input session is one that should be used. Long ago (around kernel 3.0.0) some changes in the bluetooth subsystem made the kernel do not fallback to input session when hid session is not supported or blacklisted. This patch restore that behaviour by making the kernel try the input session if hid_add_device returns ENODEV. The patch exports hid_ignore() from hid-core.c so that it can be used in the bluetooth subsystem. [1] https://bugzilla.kernel.org/show_bug.cgi?id=39882 Signed-off-by: Lamarque V.

When nonblock read the condition check (file->f_flags & O_NONBLOCK) always be true, signal_pending and device exist checking never get a chance to run, so the user mode code always get EAGAIN even if device removed. move nonblock mode checking to the last can fix this problem.

2012-11-19HID: i2c-hid: introduce HID over i2c specification implementationBenjamin Tissoires
Microsoft published the protocol specification of HID over i2c: http://msdn.microsoft.com/en-us/library/windows/hardware/hh852380.aspx This patch introduces an implementation of this protocol. This implementation does not includes the ACPI part of the specification. This will come when ACPI 5.0 devices enumeration will be available. Once the ACPI part is done, OEM will not have to declare HID over I2C devices in their platform specific driver.

2012-11-15HID: multitouch: fix Win 8 protocolBenjamin Tissoires
The Win 8 protocol specify the fact that each valid touch must be reported within a frame until it is released. We can therefore use the always_valid quirk and dismiss reports when we see duplicate contacts ID. We recognize Win8 certified devices from their vendor feature 0xff0000c5 where Microsoft put a signed blob in the report to check if the device passed the certification.
