X window don't read my input device automatically

X window don't read my input device automatically

[guo jerry]

Hi all,
        I have written my multi-touch panel device driver and register
two input devices.
        they appear in /dev/input/event7 & /dev/input/event8. The
problem is that why
        X window can read other mouse devices automatically and work under X
        environment but the device driver written by my own cannot.
        I guess that if the evbit and keybit which I set is not correctly.
        I set my evbit & keybit as following:

        input->evbit[0] = BIT_MASK(EV_KEY) || BIT_MASK(EV_ABS);
        input->keybit[BIT_WORD(BTN_TOUCH)] = BIT_MASK(BTN_TOUCH);

        I'd like solve the problem first then take into issue  that how to make
        multi-touch work in MPX.

        Thanks in advanced.

I don't think you want 'logical or' here but rather a bitwise one.
