Ubuntu won't recognize my new Logitech C930e webcam fully. Guvcview does (see below). Logitech says it supports UVC 1.5.

I found: http://sourceforge.net/p/linux-uvc/mailman/message/31645720/

Why isn't it integrated in Ubuntu 14.04 (cheese app)?

I need this camera for SimpleCV (which won't recognize it as well).

I figured out:

cam = Camera(0)  // -> for the internal notebook (edge 130) webcam
cam = Camera(1)  // -> for the Logitech C930e

I receive following errors:

SimpleCV:1> cam = Camera(1)

VIDIOC_QUERYMENU: Invalid argument

and with an openCV command:

SimpleCV:2>  cap = cv2.VideoCapture(1)

  • Yes, it's installed. Guvcview recognizes the cam, but ubuntu and simplecv not.

  • Seems this stuff is already there: "build-essential ist schon die neueste Version. build-essential wurde als manuell installiert festgelegt. linux-headers-3.13.0-24-generic ist schon die neueste Version. linux-headers-3.13.0-24-generic wurde als manuell installiert festgelegt. 0 aktualisiert, 0 neu installiert, 0 zu entfernen und 22 nicht aktualisiert."

  • I can switch to it over settings. But as soon as I set anything else then 320x240 it says: "Error while processing signal".

  • The logitech C930e records 1080p.
