Trying to use my Logitech QuickCam Pro 4000

Last night I got my Cannon A60 working bny using gphoto2 and a well placed chown command.

Tonight I'm trying to get my webcam to work, its a usb Logitech Pro 4000.  I see the "came" package, from linuxbrits website (ironically a website ive learning stuff from for the past year).

I see my quick cam shows up as /proc/bus/usb/003/004.  But I don't see it under /dev/s*.  Thats what happened to my A60, but it turned out the A60 uses a non-standard usb protocol (which gphoto fortuneatley natively speaks).

I did a search on this board for "quikcam" and surprisingly found 0 hits.  :-(

I tried following the recent "Usb mass storage thread", but the quikcam did not show up as a scsi drive.

I'm not sure what to do next. 

Any suggestions?

Re: Trying to use my Logitech QuickCam Pro 4000

Ok, I did this command:

    xawtv -hwcan

which produced:

=====================================

[root@ant23 root]# xawtv -hwscan
This is xawtv-3.91, running on Linux/i686 (2.6.4)
looking for available devices
port 77-77
    type : Xvideo, image scaler
    name : NV10 Video Overlay

port 78-109
    type : Xvideo, image scaler
    name : NV05 Video Blitter

port 110-110                            [ -xvport 110 ]
    type : Xvideo, video overlay
    name : NVIDIA Video Interface Port

/dev/v4l/video0: OK                     [ -device /dev/v4l/video0 ]
    type : v4l
    name : Logitech QuickCam Pro 4000
    flags:  capture 

[root@ant23 root]#

=====================================

So then I did a:

[root@ant23 root]# xawtv -c /dev/v4l/video0
   
Which looked like it was going to work, but the window was blank.  I will play around with it some more.

thx

Re: Trying to use my Logitech QuickCam Pro 4000

maybe i need to "force" a driver to load as mentioned here:

http://seismo.ethz.ch/linux/webcam.html

maybe i get the driver from here:

http://www.smcc.demon.nl/webcam/

?

[EDIT]

Hmm, lsmod shows module "pwc" already loaded.  I wonder hwow that happened.  Or what I do next.  :?

Anyone know how I can get my /dev/v4l/video0 device back?

I want to take snapshots with my webcam.

Have you tried Hotplug?

Re: Trying to use my Logitech QuickCam Pro 4000

Yep, I ran "hotplug usb" as root, and it didnt appear to do anything.  I tried v4l-conf and "xawtv -hwscan", nothing changed.  Maybe I'm running it wrong?

Re: Trying to use my Logitech QuickCam Pro 4000

I got the webcam working.  I had to do this command:

modprobe pcw

and also chown /dev/v4l/video0 to my user account.

I'm using the 'webcam' application. 

thx!
