Hi,
I have an old webcam, a Compro PS39U. By windows it's recognized as
vicam and works with the vicam driver. With Linux it didn't work.
lsusb showed that it identifies different than camera's recognized by
the vicam driver. So I added the usb id to vicam.c, and it now
produces images through the driver under Linux too. It's still a
shitty camera though.
I'm submitting the change, maybe someone else has this camera and
want's to use it.
Regards,
Bas

Although this is really a trivial patch, it would be nice if you can
sign your patch (on our wiki you can have more info about patch
submission procedure:
http://linuxtv.org/v4lwiki/index.php/How_to_submit_patches). Basically,
you should send at the email a line with:
Signed-off-by: Your name <[email protected]>
Also, it would be nice if you add a comment above the new entry at vicam
PCI table a short comment describing the new device, like, for example:
/* Compro PS39U */

You want to fix your mailer, it word wraps.

Description:
Trivial patch to make Compro PS39U WebCam work with linux by using the vicam driver.
The camera is just a vicam with another USB ID, so I added that ID to the driver, and it works now.

Do you get the release call back warning when rmmod the vicam module?
I tried to fix this ages ago, but all I successfully achieved was
kernel oops:
http://www.ussg.iu.edu/hypermail/linux/kernel/0510.3/1113.html
It would be nice to fix.

No sorry, I worded it all wrong. I meant on modprobe. I then attempted to
fix the code, which produced kernel oops, so it was my bad code that caused
it - it needs someone that knows what they are doing ;-)

After my attempted fixes, this is when my kernel crashed.

I don't use mine now, but it would be nice to get this code brought up to
date.

Every program has two purposes:
one for which it was written and another for which it wasn't.
