Logitech webcam (quickcam) driver issues

Jinouchi · 11-11-2009, 11:12 PM

After a few months of trying to get this webcam working during my free time (what little of it I do have), I managed to get a generic driver installed, and Skype even recognized it. I was ecstatic. The excitement was short lived, however. Within about 20 seconds of trying to test the webcam, there came several system beeps and the following message on my open terminal window (I've also included the relevant portion of dmesg done just a minute earlier)

Code:

I assume the driver crashed? Anyway I'm not sure what all this means... Should I try to find a different driver?

Hi, I also have a Logitek quickcam.

Check it's in the usb list...
lsusb

Code:

glenn@GamesBox:~$ lsusb                                                          (13-11 07:30)

And check if the module is loaded...
lsmod

Code:

glenn@GamesBox:~$ lsmod | grep gspca                                             (13-11 07:50)

glenn@GamesBox:~$

see how you go.

Yep, both are there: (I've cut out the irrelevant parts)

Code:

I notice you're using a different driver. Where did you get yours from? Our cameras appear to be in the same family, perhaps your driver will work for my camera as well.

EDIT: I managed to find the gspca driver that your using in a linuxjournal.com tutorial ( http://www.linuxjournal.com/video/ge...-working-gspca ). I'll try it out and keep you updated.

The modules are built into the kernel.

Might be, add it to /etc/modprobe.conf or /etc/modprobe.preload

If you have trouble with the old module, blacklist it in

/etc/modprobe.d/blacklist....
