From aea6a46122a0ce65a831fd93cac6d2084ac666f9 Mon Sep 17 00:00:00 2001 From: Aristeu Rozanski Date: Thu, 10 May 2007 01:47:18 -0400 Subject: Input: psmouse - add support for Cortron PS/2 Trackballs Cortron PS/2 Trackballs (700-0001A) report the 4th button using the 4th bit of the first packet (yes, it breaks the standard PS/2 protocol). This patch adds an extra protocol to generate BTN_SIDE based on the 4th bit. There's no way to detect those trackballs using any kind of special sequence, thus the protocol must be activated explicitely by writing into 'protocol' sysfs attribute: echo -n "cortps" > /sys/devices/platform/i8042/serio1/protocol Signed-off-by: Aristeu Rozanski Signed-off-by: Dmitry Torokhov --- drivers/input/mouse/psmouse.h | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/input/mouse/psmouse.h') diff --git a/drivers/input/mouse/psmouse.h b/drivers/input/mouse/psmouse.h index 3964e8acbc5..27a68835b5b 100644 --- a/drivers/input/mouse/psmouse.h +++ b/drivers/input/mouse/psmouse.h @@ -88,6 +88,7 @@ enum psmouse_type { PSMOUSE_LIFEBOOK, PSMOUSE_TRACKPOINT, PSMOUSE_TOUCHKIT_PS2, + PSMOUSE_CORTRON, PSMOUSE_AUTO /* This one should always be last */ }; -- cgit v1.2.3
