Then a USB webcam is the easiest thing to do.  For example anything listed
as having a Linux driver on this list should be able to be made to work in
less than an hour.

had success with both the Live! cam notebook pro and the Live! cam Notebook.

If you dead set on quick capture you are probably going to have to make your
own board and write your own driver with a module like this...

Ok, thanks. I'm gonna go with an USB camera then and connect it to the
24-pin connector.

I've spent more than a week trying to add V4L modules to my verdex  
kernel build, but still am getting no .ko files generated. How did you  
manage to get a USB webcam going in under an hour?

Thanks,
Chuck

1. I used buildroot (my personal opinion is that open embedded is convoluted
and difficult.)
2. edit target/device/Gumstix/verdex/linux.config enable the following...

    #CONFIG_VIDEO_V4L1 is not set

    #
    # V4L USB devices
    #
    CONFIG_VIDEO_USBVISION=m
    CONFIG_VIDEO_USBVIDEO=m
"""
3. write a make file for your usb camera driver if it isn't already in the
build tree...  here is mine for the GSPCA driver...

hi Pete,

i'm trying to get your makefile going with buildroot -v1614. Since i'm a
n00b, could you please tell me were exactly i should drop this make file?
Also when you mention "top-level" Makefile for "TARGETS+=gspca", where do I
find this? 

thanks,
hypo
