Post Help with Logitech Quickcam USB Camera
Hello,

I'm new here, but I did a lot of searching and working first so hopefully won't get booed right away. I got a Logitech Quickcam from goodwill a couple weeks back and am having a few issues with it; I'm hoping someone has an idea of what to do.

ZM is running and works great through another Wanscam IP camera. Worse case, I'll just buy more of those, but this webcam was $3 so it was worth the shot. I found that the cam is connected to the box:
Code:
freddythunder@crunchbang:/var/log$ lsusb
Bus 002 Device 003: ID 046d:08ad Logitech, Inc. QuickCam Communicate STX

And that the driver is in existance:
Code:
freddythunder@crunchbang:/var/log$ lsmod | grep "gspca"
gspca_zc3xx            36804  0
gspca_main             15775  1 gspca_zc3xx
videodev               25605  1 gspca_main
usbcore                99329  8 snd_usb_audio,snd_usb_lib,gspca_zc3xx,gspca_main,usb_storage,ohci_hcd,ehci_hcd


But when I try to take a snapshot of what the camera sees via this command:
(tried to post link but forum won't let me)
vgrabbj -l 10 -C -f testpic.jpg -d /dev/video0 -F 4

It reads "Forking for daemon mode", creates the file with 0 bytes, and the log reads:
Code:
Dec 22 22:00:47 crunchbang vgrabbj[2832]: vgrabbj started, reading from /dev/video0
Dec 22 22:00:49 crunchbang kernel: [ 1461.208039] zc3xx: probe 2wr ov vga 0x0000
Dec 22 22:00:50 crunchbang kernel: [ 1462.040050] vgrabbj[2832] general protection ip:b7753ca1 sp:bf83fa1c error:0 in libc-2.11.3.so[b76df000+140000]


When I try to run ZM, I get all kinds of corrupt JPEG data messages, but that shouldn't stop me from seeing anything right? The light on the webcam doesn't turn on (like it did when I tested the camera on a Windows machine just to make sure it works) and it's jut a black square if I look at the monitor...

edit: And, by the way, the system is headless, so I'd have to see the webcam work (or a snapshot moved to the web folder) via http...
Any help is much appreciated!!

PS: A viable answer is "Throw away the webcam" ;)
