are there any webcam experts?

I have tried many suggestions and many different times to get my webcam working under Ubuntu. It is a logitech. Is anyone willing to take a shot at getting it to work? I want someone with Linux expierence and someone who has got his or her own webcam working to help me get mine working by using remote desktop to see my screen with VNC? VNC is already set up. Contact me by instant messenger or email or any other way. All of my information is on my profile.

I have tried many suggestions
...including not replying back to a fellow LQ members reply in your earlier webcam question. Grand.
Since you "have tried many suggestions" maybe you could list them, and where you failed, so we don't have to repeat efforts?

It is a logitech.
Knowing the Vendor/Product ID tag, that's the first thing one needs to make it work.

Sure. First thing is to search LQ for threads about your webcam and check the HCL. If nothing turns up then try to find out more about the chipset from the documents that came with it, the vendors site and searching teh intarweb. Even emailing the vendor asking for used chipsets does work sometimes. If nothing turns up then start by plugging in the device, use "lsusb" or "usbmodules" command to see if any modules got loaded and look at your syslog (most likely /var/log/messages) for messages about USB. If it returns any info like Vendor ID strings use that to search the Linux-USB device overview website.
If you're going to post (error/log) messages make sure you post *exact* ones.

No thanks. Simple rule: ask a question here, get answer here.

It's been a while, but now I am trying again. I tried to compiling the spca5xx driver. I tried hwinfo to get more information. I tried many programs that should use it such as with GnomeMeeting with video4linux, amsn, one I think that was included with the spca5xx driver, and another program. It has been a while, so I can't remember everything.

Is this information useful? It is all I have. I do not have the box or any receipts because the webcam is at least 4 years old. It looks like a standard Logitech webcam that has one feature besides capturing video, twisting the front for focus.

Code:

[root@localhost ~]# lsusb 

Bus 002 Device 001: ID 0000:0000  

Bus 001 Device 003: ID 046d:0840 Logitech, Inc. QuickCam Express

Bus 001 Device 001: ID 0000:0000  

Bus 001 Device 002: ID 046d:c501 Logitech, Inc. Cordless Mouse Receiver

[root@localhost ~]#

Is this "046d:0840" useful for anything? A while back, someone told me it was.

What can I do without the model number? That's part of the problem I that I am trying to work around. I did search "046d:0840" here.

Have you tried the pwc driver? I've got a couple of old Logitech webcams and they work nicely with this driver.
