The machine has tree buttons connected to an EC that acts as a regular AT-compatible keyboard controller. It can be either in "Windows 7" or "Android" mode. It boots up with the earlier, but the Android build on the tablet switches it on bootup (Windows presumably leaves it as-is). The "Windows 7" mode, the behavior is very inconvenient: the Home button emits multiple key presses that presumably do something in Windws 7 while the second button toggles the RF Kill Switch in addition to producing a scancode (it's labeled "Back" on Android version of the tablet). The "Android" mode just sends the good ol' scan codes and this patch handles them. On mainline Linux, the "x86-android-tablets" driver makes sure we're in the correct mode. |

Files in this directory specify a description of hardware devices, in the form of mappings from modalias-like keys (which identify specific hardware devices) to udev properties. Files in this directory are not read by udev directly. Instead, man:systemd-hwdb(8) compiles them into a binary database. See man:hwdb(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of the udev daemon. Use 'systemd-analyze cat-config udev/hwdb.d' to display the effective config.
