Trackpad Issues

[L-Ryland]

處摸板剛開機可用，使用一段時間後停止響應。重啟後依然無反應。

这个log没有显示错误，WCOM488F 触摸屏是故意让它以 polling 模式运行的。

先确定下 /Library/Extensions 有没有 VoodooI2C 相关的 kexts，如果有就删了。然后重建缓存 sudo kextcache -i / 试一下，如果没有用，可以试试 tiger511 修改的版本，如果还不行，那就用回 VoodooI2C 2.3 吧，这个稳定，虽然 kernel_task 占用比较高。

試了一下 修改版不起效, 2.3版本觸摸屏可用, 觸控板依然不響應。

可以试试这个 I2C.zip

Put the both the Touchscreen and touchpad in GPIO mode with ACPI patch.Then try the following kext. It will enable GPIO pinning for both. MultiGPIO_patch.zip
