Hi, Please review and consider to apply my patch, for following reasons: 1. Nobody complains anymore about it :) 2. Tested to guarantee working with 2 kinds of Logitech webcam. 3. It's quite clearly to see that event input support won't break anything existing (and you still have option to disable it in kernel configuration if you don't like). 4. Consistency of webcam snapshot button support as an event input device with other webcam drivers. 5. Nowadays, many manufacturers are making webcams with a button on it to use in their Windows software (e.g. the software Logitech's Quickcam for Logitech webcams). The webcam snapshot button is very convenient when you want to take an interesting moment on someone or something by one hand (like a digital camera). I've asked a question about this problem and it seems that solutions are still null for Linux. But now I'm happy because I've found the way to use webcam snapshot button with webcam applications (like Cheese) provided that my webcam button is supported as an input device. ---------- Sharing my experience on Ubuntu 8.10 1. Install gizmod (http://gizmod.sourceforge.net) sudo apt-get install gizmod 2. Connect webcam and run gizmod at debug mode as superuser: sudo gizmod -g 3. Open webcam with Cheese and press the snapshot button (button of pwc webcam is only usable when webcam is being open) When button is pressed, gizmod shows: onEvent: Standard -- /dev/input/event12 | [EV_KEY] <BTN_0> c: 0x100 v: 0x1 and when button is released, gizmod shows: onEvent: Standard -- /dev/input/event12 | [EV_KEY] <BTN_0> c: 0x100 v: 0x0 Pay attention to "c: 0x100 v:0x0" in the above line, we'll use these numbers to configure gizmod. 4. Create /etc/gizmod/modules.d/010-Snapshot-Cheese.py with the following content (the numbers 0x100 and 0x0 are used): #*** #********************************************************************* #************************************************************************* #*** #*** GizmoDaemon Config Script #*** Snapshot Cheese config #*** #***************************************** #***************************************** #*** """ Written by Pham Thanh Nam (phamthanhnam.ptn@xxxxxxxxx) """ ############################ # Imports ########################## from GizmoDaemon import * from GizmoScriptRunningApplication import * import subprocess ENABLED = True VERSION_NEEDED = 3.2 INTERESTED_CLASSES = [GizmoEventClass.Standard] INTERESTED_APPLICATION = "cheese" ############################ # SnapshotCheese Class definition ########################## class SnapshotCheese(GizmoScriptRunningApplication): """ Snapshot Cheese Event Mapping """ ############################ # Public Functions ########################## def onDeviceEvent(self, Event, Gizmo = None): """ Called from Base Class' onEvent method.

Kill gizmod by Ctrl-C and run it again at normal mode: sudo gizmod 6. Focus to active Cheese window, uncheck countdown option in Cheese and try the snapshot button.
