With cpia 1.3.1 on a 2.6.0 kernel, I get the following:

Jan 1 16:21:29 pc videodev: "CPiA Camera" has no release callback. Please fix your driver for proper sysfs support, see http://lwn.net/Articles/36850/
Any known fix for the above issue?
Thanks
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
It looks like nobody is updating the cpia driver to the 2.6 kernel -- that's too bad, because the modifications needed are likely very minor. The 2.6 kernel's use of sysfs may be the issue, as dmesg suggests.
I just sent a bug report to lkml but it would be nice to hear from someone who knows the driver. Duncan Haldane, who used to update the driver, has been quiet for a year now.
Cheers,

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I also get this error with the 2.6.27 kernel. However, having plugged the microscope in, it's registered to /dev/video0. If I then:
sudo ln -s /dev/video0 /dev/video
and then launch gqcam, my microscope works! So there is still a bug in the driver, but it doesn't seem to prevent the microscope from working, at least under 2.6.27 kernel (ubuntu 8.10).
