   @gibor, this works for my Logitech Quickcam 4000 Pro - many thanks for your help.

   Is this package going to replace the one in the repos?

   @gdesilva
   Maybe I did not understand the question, but the original package linux-2.6.37.tazpkg contains the kernel and kernel modules standard, this new the same and others added from compilation.
   The weight difference is discrete 3.7 Mb 9.2 Mb against, but here we are finished automatically other modules you need me (bluetooth rfcomm vboxdrv ftdsio video firewire ieee1394 rfkill ).
   To lighten it could remove all the extra modules (find compare to original and removing on /lib/modules/2.6.37-slitaz), preserving only related pwc, or do the same operation with a kernel recompilation and repacking with original unmodded slitaz-kernel.

   Just noticed that if the camera is plugged in at boot time pwc load fails. As mentioned by pipein above removed pwc, videodev and v4l1_compat and reloaded them in the order of v4l1_compat, videodev and pwc and then the load works OK and the camera works OK too. It appears the sequence of loading the modules is important for pwc to work.

   hi
   i have problem with webcam in slitaz 4. (there was no problem with slitaz 3)

   when i try to follow T0N1 structures
   make modules
   and
   make modules_install
   commands are giving error and restarting openbox and asking user name and password.

   my question is is it possible to get bzImage who is compiled?

   thanks

   @romano, just download the package mentioned in gibor's post above and install it. That should install the correct drivers. I have tried it and it works for me.

   Just an update.

   Tried using 'modprobe=v4l1_compat,videdev,pwc' on grub command line and then the pwc loads OK and overcomes the need to remove those modules and reload them. I guess using on grub command line assures the correct order of loading the modules.

   @rmoano - your 'thank you' should go to gibor who made these modules available ;-)

   Hi,
   I'm also having issues trying to set up my webcam.
   Computer: eee701. Webcam is internal: lsusb gives 'eMPIA Technology, Inc. EEEPC 701 integrated Webcam'
   I eventually managed to install v4l (there seems to be a bad link in one of the packages, it installed all sorts of other bits and pieces but complained of not finding that) and got to the point where opening any camera-related software (Skype or ucview) caused a kernel panic.

   I understand that I should (a) recompile the kernel or (b) install the .tazpkg file linked to above, but I've not managed to do either.
   When I follow the instructions on http://doc.slitaz.org/en:guides:kernel I get as far as 'make oldconfig', at which point I get the error "No rule to make target 'oldconfig'. Stop."
   Trying to install gibor's file with 'tazpkg install linux-2.6.37.tazpkg --forced' gives the error "can't open '/tmp/tazpkg-4824/19640/receipt'"
   Can anyone suggest how I should proceed from here please? Repeated searches of the forum posts haven't yielded me anything so far (apart from a few unanswered topics).
   I know only a little about Linux - I'm an Xubuntu user who generally just follows others' instructions!

   Many thanks

    Just curious, did you install v4l-dvb-development_2.6.37?

    With regards to installing gibor's package, are you running the tazpkg command from the directory where the downloaded file exists?

    @nht, it appears that eeepc 701 integrated cam uses the uvcvideo driver. Is this the module you are using? Interesting to see what driver has been loaded - output of lsmod will be useful. If you are using uvcvideo then as suggested by pipein here in this thread, try removing(modprobe -r) uvcvdieo (or whatever is currently loaded), videodev and v4l1_compat and reload (modprobe ) them in the order of v4l1_compat, videodev and uvcvideo.

    Hello community and tanks very much for Slitaz
    I follow this thread but the output I get from fswebcam and mpalyer
    is diferent than the posted by gdesilva at begining of this tread using
    a Logitech QuickCam.
    I don't know if this better or worst.

    And installing the gibor's package I get the the same error as nht:

    Hi after seeing the problem that happens to some of you, I created a new package with the uvc and pwc driver.

    http://www.freefilehosting.net/v4l-dvb

    double click install or tazpkg install v4l-dvb.tazpkg

    for testing then on terminal

    tazhw box
    choice webcam
    at end of process ask if you test webcam>yes
    and appears webcam live on window

    thats it all.
