jwin webcams: supported under linux?


i recently got a jwin webcam and I'm wondering if it will work with linux. I'm sure there is a way it will, I just don't know what to do yet.
my kernel version: 2.6.27.7
What commands should I run to show more information?

Well, it might be working already. What happens when you plug it in and run the application cheese ?
If cheese doesn't see it, we need to know more about it: Unplug the cam. In a terminal lsusb.
Plug in the cam, then in a terminal lsusb again.
The addition to the output from this command, compared to the previous one, are the details of your webcam. Tell us what they are.

Another thing to try: Unplug your cam. Plug it back in. Type dmesg in a terminal, and post the last 20 lines here.

Sorry to bump this, but I have the same issue with Debian Lenny (I might upgrade to squeeze if it's warranted, but I'm not sweating it).

lsusb:
Code:
tux@beast:~/freeciv-2.2.7$ lsusb
Bus 001 Device 003: ID 093a:2620 Pixart Imaging, Inc. 
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
tux@beast:~/freeciv-2.2.7$
dmesg:
Code:
[11508.392092] usb 1-2: new full speed USB device using ohci_hcd and address 3
[11508.596831] usb 1-2: configuration #1 chosen from 1 choice
[11508.685507] usb 1-2: New USB device found, idVendor=093a, idProduct=2620

It looks like this camera needs the gspca_pac7311 module:

Plug in the camera.
Code:
lsmod | grep pac7311
Is the module listed?
If so, fire up cheese:
Code:
cheese
If not, then load the module (as root)
Code:
modprobe gspca_pac7311
Try cheese again. Re-plug the camera, try cheese again.

Had no go. Here's dmesg again:
Code:

I used gspca-source, do I need a special kernel module? I tried Debian's binary with no luck.

It looks like you need the gspca_pac7311 module for your camera.

I have no idea what you mean. Which "Debian's binary" ?

If your version of debian doesn't provide it (the modprobe gspca_pac7311 will give you an error message if it does not exist) then you have two choices:

- Try a different distro which provides the module automatically. Maybe try a live CD of a current distribution. (Ubuntu 10.04 [kernel 2.6.32-33-generic] lists that module as available, but I do not have a camera like yours to test it out).

- Download the source code for gspca_pac7311 and compile it against your current kernel's source code (more stuff to download, but it's not that difficult, error messages will help you resolve dependencies). Then you can modprobe gspca_pac7311 to make it work.

Hope this helps.

With Ubuntu, kernel 2.6.32-21-generic, the webcam is recognized but I get no input from it from cheese.

What makes you think that it "is recognised"?
See the advice in post #4

Sorry to bump

I was able to plug the webcam in and get a response in Cheese, but my problem is that my feed (or stream, or whatever it is called) is upside down. I tried repositioning the camera but I can't get the camera to stay with it turned upside down. Is there any way to get the feed flipped so that it is showing the correct orientation?

Welcome to LQ!

This thread is very old, and you will get a better response if you start a new one with a sensible title.

Please include details of your cam as listed by the output of the lsusb command in a terminal, along with details of the version of linux you are running (Eg "Mint 16", "Debian Wheezy")
