Did you "make install" the v4l tree you built against and make sure none
of the old video modules were loaded (see lsmod) when you modprobe'd
gspca?

Thanks,

I checked the installed versions of videodev and gspca and both are
the same versions as the versions in the build directories, so they
installed fine.  I also checked the depends for videodev, v4l2-common
and v4l1-compat, and those were also the correct versions.

I double checked to make sure there weren't any modules left over in
other directories in /lib/modules/`uname -r` and didn't find any.

Since the machine in question also has a PCI video4linux device in it,
the drivers for that card already load the videodev modules.

Something isn't quite right, the latest driver 20071224 is OK on the

Am I pulling the source from the wrong place?  It came as a tarball.

Looks AOK. Mine built using "make clean && make && make install" for all 
kernels, latest 2.6.24-git22.

I downloaded the latest 2.6.24 ubuntu kernel, built it and installed it.

Unfortunately, I still get the same errors when I try to "modprobe gspca":

[   57.028476] gspca: disagrees about version of symbol video_devdata
[   57.028481] gspca: Unknown symbol video_devdata

I tried getting the latest v4l-dvb hg tree to see if that would help
but it failed to compile:
