webcam - HP655

English Hardware
#1

I have a laptop (hp655 internal web camera, SUSE12.2 KDE4.8.5). When I start the camera, the system crashes.
Can you help me?

#2

What application do you use that causes this system crash ? How much of the openSUSE-12.2 system crashes ? The entire desktop ? GNU/Linux also ? What are the crash symptoms?

What graphic driver is your openSUSE using ? What webcam driver do you believe your openSUSE is using ?

What can you tell us about your webcam ? What is the output of the following command typed in a terminal:


lsusb

in particular we are interested in the lines associated with the webcam.

can you ssh into the laptop at this time (with the system ‘freeze’ ) ?

Do you recall if you had the same behaviour with the radeon graphic driver ?

If I read that correctly, your webcam is a 090c:237c.

I read no mention of uvc compatibility on this page: Linux UVC driver & tools

Have you succeeded with any GNU/Linux distribution to get this webcam to work ?

Does your ‘dmesg’ provide any hints as to the problem , either when the driver is loading (or failing to load) or when the freeze occurs ? Do the other log files (when the freeze occurs) provide any hints.

You could check with the uvc mailing list to see if they provide guidance as to getting your webcam to work with the uvc webcam driver.

In particular, using the referenced FAQ page as guidance, send the following command to confirm your webcam is UVC compatible :


lsusb -d 090c:237c -v | grep "14 Video"

As noted in the FAQ:

If your device is a UVC device, you should see a number of lines that look like this:


bFunctionClass         14 Video
bInterfaceClass        14 Video
bInterfaceClass        14 Video
bInterfaceClass        14 Video


In this case the Linux UVC driver should recognize your camera when you plug it in. 

If there are no such lines, your device is not a UVC device.

The laptop was not mine and had to quickly fix the problem.
I installed USU8.1 - Bulgarian distribution based on ubuntu. The camera works without any additional settings.
Thank you very much oldcpu!

Glad to read its working now.

Those commands will work on any GNU/Linux distribution. Sharing the output might help those with a similar problem.
