Hi, > You could start with making the hid-recorder output available... Ok. For reference: <https://motorola-global-portal.custhelp.com/ci/fattach/get/593562/1361474625/redirect/1/session/L2F2LzEvdGltZS8xNDM3NjUwMjg3L3NpZC9reU9zZTRzbQ==/filename/SmartControler_Eng_SP_Fr_68016304001C.pdf> <http://ecx.images-amazon.com/images/I/61EzkJ7jmpL._SL1200_.jpg> There are four buttons on the front. "Burger Menu button" pressed E: 1020.868306 4 01 00 00 e3 released E: 1021.065924 4 01 00 00 00 "Home button" pressed E: 967.576417 4 01 00 00 4a released E: 967.907627 4 01 00 00 00 "Back button" pressed E: 1115.066579 4 01 00 00 29 released E: 1115.292091 4 01 00 00 00 "Search button" pressed E: 1140.136426 4 01 00 00 65 released E: 1140.306423 4 01 00 00 00 Next, there's a volume slider and a mute button on the left side. "Volume up" pressed E: 1246.894763 4 03 00 80 00 released E: 1247.816149 4 03 00 00 00 "Volume down" pressed E: 1270.319676 4 03 00 00 01 released E: 1270.518170 4 03 00 00 00 "Mute" no output, probably not handled by HID subdevice. Part of the headset subdevice? How do I capture those events? Finally, the big black trackpad on the top, above the four buttons. When I move my fingers on that trackpad, hid-recorder will output lots of raw HID data. How do I group these so that it's useful?
