Trust Spyc@m 500 on Debian

Allowee · #1 28-Jan-2004, 03:49

I've been trying and trying but for some reason i can't get my webcam to work..

I've been Googling but nothing really helped me.
my system does not detect that I've plugged in my webcam, so I can't connect to it.

I have drivers installed for usb as stated on some pages, but still no luck

webcam: Trust Spyc@m 500
system: Debian

Hey Allowee. I have never hooked up a webcam in Linux, so I don't have any groundbreaking advice, but a couple of questions came to mind.

First, do you have any other USB devices that do work on Linux?
If so, then the USB system is working.

Now, can you find an entry for your webcam under /proc/bus/usb?
If so, this may tell you more about the device as far as chipset, etc.

If you know what chipset it uses then maybe one of these drivers will work:

OV511 Driver
a driver for the OV511, a USB-only chip used in many "webcam" devices. Any camera using the OV511/OV511+ and the OV6620 or OV7610/20/20AE CCD should work. It supports streaming and capture of color or monochrome video via the Video4Linux API

SE401 based USB webcams
a driver for the EndPoints/Aox SE401 usb webcam chipset

I will keep looking to see if I can find out anything about this.

I never really used any usb devices...

and I think I have a problem..
/proc/bus/usb is empty, no matter what I do

I guess something is wrong with my usb system...

Sorry, Allowee, I am a moron. I didn't have access to a current linux install when I said that it should show up under the /proc/bus/usb directory. I don't believe that is used for hotplug devices. On my system, I have a directory called /etc/hotplug that handles this.

Anyway, look through your kernel configuration file and see what you have as far as USB support. I think that you are going to have to enable Video For Linux (which is not enabled by default I believe) and I load my USB support as a module. There are a few webcam drivers that you can try out as well in the kernel. Actually what kernel version are you running. I am on 2.4.21 right now so yours may be a little different.

Also, do you have any idea what chipset that your webcam uses? I did a google on it and everything showed up in German...

I'm still not sure about the chipset... looking for a manual now (cam used to be from my sister)

but I've now found a script that will load the usb system, /etc/hotplug/usb.rc
doing and usb.rc status gives this:

Code:

./usb.rc status

looking at that it seems i have the video drivers loaded

dsmith · #6 28-Jan-2004, 11:54

Great. It appears that your webcam is based on the stv680 chip. And it is automatically loading the drivers.

I found this link that has a bunch of utilities etc. for this camera under linux.

Have you checked to see if v4l (video for linux) is loaded? I am not 100% sure what this is to tell you the truth, but everytime I look at something to do with a webcam, I find this mentioned.
