Thanks in advance

Logitech's Quickcams are pretty well supported. I have a webcam at home on my server and I use the webcam script that comes with XawTV successfully along with Apache. I haven't gotten it to work with any IM clients, but that's no problem as I can just point their browser to that URL and it refreshes at the rate that I want it to.

There's a lot of documentation on Logitech webcams in Linux listed in Google searches.

I have a logitech quickcam express and am running redhat 9 and cant seem to get it to work ........
when I run xawtv I get the reply /dev/video no such image grabber found or something to that effect.

I tried installing the third party drivers found on google but I always get a pointer error when trying to compile.

any clues as to what i need to do......?

sounds like everyone has a webcam working but me....lol

My webcam is stop working too. It's a Logitech quickcam pro 3000. It has been working fine on my SuSE linux rig. Now, I cannot use xawtv / motv / gnomemeeting

When it works it was just worked without doing anything. I think the culprit is the kernel module. Somebody knows to make it work on me too? I use SuSE linux 8.2 now.

dmesg | grep usb

Running at 1280x1024@32bit True color???

Anybody know how to make it works at 640x320?

That's what I can read on the top of the window beside the icon in +- a second:
xawtv then changed to
1280x1024, 32 bit TrueColor (...) then
??? and stays like this with green green grass of death :-(

I think that's not the real output, because when I change the desktop resolution to 1152x864 it'll show that.

I don't know how to make it work yet. I've tried kernel module recompile (to get a new pwc.o and copy it to the working kernel's module dir.) and enable all usb type (ohci, uhci,...) detection in the kernel with no success :-(

I can see the three question marks on your screenshot too ;-) That's not good enough -> it should say Logitech Quickcam ... No?
You must shot that using a nice digital camera.


Seaking more fun :-)

pwc Also supports the Askey VC010, various Logitech Quickcams, Samsung MPC-C10 and MPC-C30,
usb.c: registered new driver Philips webcam
pwc Logitech QuickCam Pro 3000 USB webcam detected.


Have fun :-)
