Hi, Being capella h/w of my p-sensor,
I customized the following => I took the HAL from htc ie. in device/htc/passion-common/libsensors /ProximitySensor.cpp and i customized acc. to my dev entries. => I registered my driver with input core. It was working with USB cable attached, but it's not working with w/o USB. Means When i put the device closed into my EAR, it's turned OFF, It's not turned ON , when i take AWAY from my EAR. I suspect that it may be sync problem with HAL vs Driver ioctl(). I attach a HAL code for reff. Please let me know any one have an idea....
