Bug Description

Most phones support remote controls built into wired audio headsets. There seem to be various types on the market offering between one and four function buttons, I for example have a pair of three-function Sennheiser CX2.00G earbuds.

Google released a specification as part of its Android project (https://source.android.com/devices/accessories/headset/specification.html), but according to some source it is incompatible with older devices because different resistor values are being used.

Last I checked we were not getting any input events for the volume buttons on the headset I tried, wonder if that's because of the incompatible impedance values. Otherwise whatever else converts the hardware events to input events needs adapting.
