-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all,
this patch adds support for some saitek mice which implement a tristate button (for switching button mappings in the official windows driver) by keeping one of three (non-physical) buttons constantly pressed. This breaks X and probably other userspace software. The patch below implements a quirk which instantly sends a release event for the affected buttons. Disclaimer: this is not entirely my own work, it is based on a patch for the R.A.T.7. which was posted here: http://us.generation-nt.com/answer/patch-2-6-38-mode-button-quirk-saitek-cyborg-t-7-help-202649672.html I merely added two usb ids and kept it up to date. - --- a/drivers/hid/hid-ids.h 2013-10-08 15:20:58.781792791 +0200 +++ b/drivers/hid/hid-ids.h 2013-10-08 15:22:17.815804729 +0200 @@ -714,6 +714,9 @@ #define USB_VENDOR_ID_SAITEK 0x06a3 #define USB_DEVICE_ID_SAITEK_RUMBLEPAD 0xff17 #define USB_DEVICE_ID_SAITEK_PS1000 0x0621 +#define USB_DEVICE_ID_SAITEK_RAT7 0x0ccb +#define USB_DEVICE_ID_SAITEK_RAT7TOO 0x0cd7 +#define USB_DEVICE_ID_SAITEK_MMO7 0x0cd0 #define USB_VENDOR_ID_SAMSUNG 0x0419 #define USB_DEVICE_ID_SAMSUNG_IR_REMOTE 0x0001 - --- a/drivers/hid/hid-input.c 2013-01-31 19:09:35.058570485 +0100 +++ b/drivers/hid/hid-input.c 2013-01-31 19:11:57.779833199 +0100 @@ -1039,6 +1039,25 @@ if ((field->flags & HID_MAIN_ITEM_RELATIVE) && (usage->type == EV_KEY)) input_event(input, usage->type, usage->code, 0); + + /* hack for Saitek RAT mice which report release events for their + * mode button on the NEXT press event: instant release + */ + if ((*quirks & HID_QUIRK_RAT_BROKEN_BUTTON_RELEASE) && + value && usage->type == EV_KEY && + /* RAT7 uses buttons 13,14,15 */ + ((usage->code >= BTN_MOUSE + 8 && usage->code <= BTN_MOUSE + 10) || + /* MMO7 uses button 20 */ + (usage->code == BTN_MOUSE + 15)) && + test_bit(usage->code, input->key)) { + input_event(input, usage->type, usage->code, 0); + /* we'll get a real release event from the mouse anyway, and + * userspace should cope with the extra input-layer + * button-up events anyway; just re-set the bit to stop + * spurious button-down events + */ + set_bit(usage->code, input->key); + } } void hidinput_report_event(struct hid_device *hid, struct hid_report *report) - --- a/drivers/hid/usbhid/hid-quirks.c 2013-01-31 19:09:35.058570485 +0100 +++ b/drivers/hid/usbhid/hid-quirks.c 2013-01-31 19:12:58.195232311 +0100 @@ -82,6 +82,9 @@ { USB_VENDOR_ID_QUANTA, USB_DEVICE_ID_QUANTA_OPTICAL_TOUCH_3001, HID_QUIRK_NOGET }, { USB_VENDOR_ID_QUANTA, USB_DEVICE_ID_QUANTA_OPTICAL_TOUCH_3008, HID_QUIRK_NOGET }, { USB_VENDOR_ID_REALTEK, USB_DEVICE_ID_REALTEK_READER, HID_QUIRK_NO_INIT_REPORTS }, + { USB_VENDOR_ID_SAITEK, USB_DEVICE_ID_SAITEK_RAT7, HID_QUIRK_RAT_BROKEN_BUTTON_RELEASE }, + { USB_VENDOR_ID_SAITEK, USB_DEVICE_ID_SAITEK_RAT7TOO, HID_QUIRK_RAT_BROKEN_BUTTON_RELEASE }, + { USB_VENDOR_ID_SAITEK, USB_DEVICE_ID_SAITEK_MMO7, HID_QUIRK_RAT_BROKEN_BUTTON_RELEASE }, { USB_VENDOR_ID_SENNHEISER, USB_DEVICE_ID_SENNHEISER_BTD500USB, HID_QUIRK_NOGET }, { USB_VENDOR_ID_SIGMATEL, USB_DEVICE_ID_SIGMATEL_STMP3780, HID_QUIRK_NOGET }, { USB_VENDOR_ID_SUN, USB_DEVICE_ID_RARITAN_KVM_DONGLE, HID_QUIRK_NOGET }, - --- a/include/linux/hid.h 2013-05-18 03:16:26.713052127 +0200 +++ b/include/linux/hid.h 2013-05-18 03:17:23.407343351 +0200 @@ -283,6 +283,7 @@ #define HID_QUIRK_MULTI_INPUT 0x00000040 #define HID_QUIRK_HIDINPUT_FORCE 0x00000080 #define HID_QUIRK_NO_EMPTY_INPUT 0x00000100 +#define HID_QUIRK_RAT_BROKEN_BUTTON_RELEASE 0x00000200 #define HID_QUIRK_SKIP_OUTPUT_REPORTS 0x00010000 #define HID_QUIRK_FULLSPEED_INTERVAL 0x10000000 #define HID_QUIRK_NO_INIT_REPORTS 0x20000000 - -- Regards, C -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJSxcSIAAoJECsSvCKD1CYc5LQH/ROXMVqulZsP1D4RTY8pL14k D4udVjVfd60PlmqYmzSfijcD1nISUEldSSdOy1lf/DJUHvvfK/Ybjl1fAeqebqdi pZZQM+2V2czdcdEB7ldT4stSig4MfHGdh/t5EGFdhIre0fXuXBV+dm9q8tcJitpn UtJqk2TzDXTOwx847Mwo4kiJ4JdgF/oLgfNOtxCClHySSrBHw/kbgCduoIn5ISx7 4JELsD7LpW+ohbOdg7XBzEZZ4XbBd4eCTr8FogJAlBQSvCiMGXO1geCCaRCzB5Xg HmULc8/zv1bE9kYHvGhRIodL8x8+De/MktFEiNOSJUw729dsO/eyW38vLvi2brQ= =g13R -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
