HP Webcam worked, but no more

[uhappo]

My laptop is HP Pavilion dv5-1035eo. When I tried my webcam in Cheese for the first time, it worked as it should and all was clear.

But when I tried it next day, it wasn't working. Also Camorama wasn't working with it.

lsusb says it's

5986:0137 Bison

And dmesg says about it

What's wrong?

Try using Ekiga see if the cam works/detected. You may have to work with the settings > Open Ekiga > Edit > Preferences > Devices > Video Devices > try changing some of the settings. (try both V4L and V4L2)

To test your webcam you can do this:
There are 6 icons on the left side of the main Ekiga window. Push the 4th button from the top (a grey round webcam). If eveything is ok, you'll see the output of the webcam. If not, you'll see the Ekiga logo bouncing slowly.

If Ekiga doesn't work post results of the command > lsusb

Hi,
I had similar issues with a webcam (logitech quickcam) it appears cheese defaults to /dev/video0 even if started with cheese -d /dev/video1 (my TV card is video0).

With camorama try changing video input to v4l in "multimedia settings" (from v4l2) and start in terminal camorama -d /dev/video1 (or whatever the webcam is).

Doug.

lsusb:

Ekiga/Camorama wasn't working, and cheese with both video0/video1 gave no moving picture, neither still pitcture.
