Headset is detected in our andorid device by using a detect gpio which is turned on when headset is inserted.If the headset is inserted right from very beginging i.e. before device is even turned on then we forcefully call the handler and thereby in handler we check if gpio is turned on or not and do the rest of things. > Once the handler is called then we find out if the headset > is there or not using gpio and then normal detection happens > > Is it the right way to detect the device during power-up? Does not linux have any other way of doing this which i may be missing? How this is handled in the case of ALSA jack i.e. the jack drivers which is using alsa framework for detection? Android doesn't use ALSA framework for reporting JACK. > > After the device is powered up and then if we insert headset > then it is working fine by calling the interrupt handler and > everything goes fine. > > linux -2.3.5 > Android Device > _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
