I own a
Code:
041e:4039 Creative Technology, Ltd WebCam Live! Effects
So I kinda half-heartedly explored the answer to this puzzle in this thread:
HTML Code:

However, as an addendum, I found some conflicting information about it listed.

Firstly, at the Linux USB device overview site:
HTML Code:
http://www.qbik.ch/usb/devices/showdev.php?id=3708
It explains there is no information about the particular webcam regarding the chipset it uses, but suspects it uses the same as the Creative Webcam Live! cam.

So I check the connect Creative site:
HTML Code:
http://connect.creativelabs.com/opensource/Lists/Webcams/AllItems.aspx
and sure enough it lists it as being 'approved' but there is no driver listed in it's info page.. Am I to suspect then it IS using the same driver as Live! (seeing as that webcam is above it in the list, and has an ID very similar.) The driver for the Webcam Live! is the spca5xx ...

So far, so good? I still haven't been able to get it to work. I checked that GSPCA driver site:
HTML Code:

BUT, It is my understanding that a working and current version of the gspca drivers have been included in the latest distros so I wouldn't need to download, would I?
