Greetings, I have a shiny new Logitech C920S USB webcam which identifies as a [-d ugen5.9] vendor-0x046d-HD-Pro-Webcam-C920 -S E0E2DC0F when running webcamd as root. I can't get /dev/video0 created. I have put in the mandatory 4 hours or so on my own with google and the man pages as my helpers, and I think I'm close, but so far no joy. I can get it specifically matched with devd via /usr/local/etc/devd/webcamd.conf (though no actions work). So for example, if I run, as root: root@feyerabend> webcamd -d ugen5.9 -N vendor-0x046d-HD-Pro-Webcam-C920 -S E0E2DC0F -M 0 webcamd: Cannot find USB device Alternatively: root@feyerabend> /usr/local/etc/rc.d/webcamd start ugen5.9 Attached to ugen5.9[0] root@feyerabend> But no /dev/video0 creation, no running webcamd, nothing in /var/log/messages etc. When I plug in the cam, I get the following in /var/log/messages: Mar 24 13:07:56 feyerabend kernel: ugen5.9: <vendor 0x046d HD Pro Webcam C920> at usbus5 (disconnected) Mar 24 13:08:23 feyerabend kernel: usb_alloc_device: Failure selecting configuration index 0:USB_ERR_TIMEOUT, port 4, addr 8 (ignored) Mar 24 13:08:23 feyerabend kernel: ugen5.9: <vendor 0x046d HD Pro Webcam C920> at usbus5 Not sure if that long timeout is significant. Any help is much appreciated. Thanks! Russell
