Hi all, I am not going to write a patch for this request before I get the permission for the new tool type. It affects all touch screen devices (under drivers/input/touchscreen) that support both pen and touch. Right now, in the user land, BTN_TOUCH is used to indicate a single touch events. BTN_TOUCH and !BTN_TOOL_PEN (http://udev.sourcearchive.com/documentation/161-1/input__id_8c-source.html) are used to determine if the device is a touch screen device or not a pen. With both pen and touch on the same logical port (serial touch screen with pen and touch enabled, refer to wacom_w8001.c), BTN_TOUCH and !BTN_TOOL_PEN will always be false, which indicates a non-touchscreen device. That is wrong. Unless we have other means to tell the user land a device is a touchscreen, BTN_TOUCH with !BTN_TOOL_PEN won't do the job for us. I've already had a value for the new type: +#define BTN_TOOL_TOUCH 0x149 This new type resolves the confusion we had for the existing serial pen and touch enabled touchscreen devices. Considering we are merging the two logical ports for USB devices, the new type is required for the future USB touchscreen support as well. Thank you for reading and your timely comments would be greatly appreciated.
