I think I need some custom config file for devd, however, something weird occured here. I tried putting following file in /etc/devd directory, and after restarting devd, webcamd is started as expected. # Acer # Bell notify 100 { match "system" "USB"; match "subsystem" "DEVICE"; match "type" "ATTACH"; match "vendor" "0x0408"; match "product" "0x3001"; action "/usr/local/sbin/webcamd -N AcerA-Bell-T231HlTouchScreen"; }; Problem is, for some reason, /dev/input/event6 file is being created, but not recognized in X, nothing logged in Xorg.0.log. When starting manually, the same file is recognized, logged as [786.720] (II) config/udev: Adding input device AcerA Bell T231HlTouchScree= n (/dev/input/event6) [786.721] (**) AcerA Bell T231HlTouchScreen: Applying InputClass "libinput = touchscreen catchall" [786.721] (II) Using input driver 'libinput' for 'AcerA Bell T231HlTouchScr= een' [786.721] (**) AcerA Bell T231HlTouchScreen: always reports core events [786.721] (**) Option "Device" "/dev/input/event6" [786.851] (II) event6 - AcerA Bell T231HlTouchScreen: is tagged by udev as= : Touchscreen [786.855] (II) event6 - AcerA Bell T231HlTouchScreen: device is a touch de= vice [786.881] (II) event6 - AcerA Bell T231HlTouchScreen: device removed [786.893] (**) Option "config_info" "udev:/dev/input/event6" [786.893] (II) XINPUT: Adding extended input device "AcerA Bell T231HlTouch= Screen" (type: TOUCHSCREEN, id 12) [786.902] (**) Option "AccelerationScheme" "none" [786.931] (**) AcerA Bell T231HlTouchScreen: (accel) selected scheme none/0 [786.932] (**) AcerA Bell T231HlTouchScreen: (accel) acceleration factor: 2= .000 [786.932] (**) AcerA Bell T231HlTouchScreen: (accel) acceleration threshold= : 4 [787.060] (II) event6 - AcerA Bell T231HlTouchScreen: is tagged by udev as= : Touchscreen [787.064] (II) event6 - AcerA Bell T231HlTouchScreen: device is a touch de= vice [809.940] (II) config/udev: removing device AcerA Bell T231HlTouchScreen [809.941] (II) event6 - AcerA Bell T231HlTouchScreen: device removed [810.056] (II) UnloadModule: "libinput" (last 3 lines are from detachment). Anybody with some hint? I need starting webcamd automatically, which seems to work, but what makes X not recognize created input file? Regards, Milan
