FYI also tried the following:

craig@Inspiron:~$ sudo service webcamstudio restart
[sudo] password for craig: 
 * Stopping WebcamStudio kernel modules                                         
 * No WebcamStudio kernel modules loaded
                                                                         [ OK ]
 * Loading WebcamStudio kernel modules                                          
 * No suitable WebcamStudio modules for the running kernel found
                                                                         [ OK ]

After more experimenting I have tried also installing webcamstudio-dkms:

craig@Inspiron:~$ sudo apt-get install webcamstudio-dkms

...

webcamstudio:
Running module version sanity check.
 - Original module
   - No original module exists within this kernel
 - Installation
   - Installing to /lib/modules/3.8.0-19-generic/updates/dkms/

depmod......

DKMS: install completed.

However when I run webcamstudio I still see the same error dialogue "None of 
the kernel modules webcamstudio/v4l2loopback are loaded... The virtual webcam 
will not be available..."

And finally I run modprobe

craig@Inspiron:~$ sudo modprobe webcamstudio

... and it is now working!

Updated my Ubuntu (apt-get upgrade) today and an updated webcamstudio was 
installed.

Having done so the "None of the kernel modules webcamstudio/v4l2loopback are 
loaded... The virtual webcam will not be available..." error returned until I 
next rebooted.

Hi,
Thanks for your info and investigation of the problem, and sorry for my late 
reply...

This is not an actual bug...

I am sorry for this annoying inconvenience, but it is a kinda design decision.
This dialog is only there to remind you that you need to install/load the 
required kernel module (this could be WCS' own kernel module named webcamstudio 
or the v4l2loopback kernel module if installed).

So WCS is split into two packages - webcamstudio and webcamstudio-dkms. And 
when you install the webcamstudio package, it recommends either 
webcamstudio-dkms or the v4l2loopback-dkms to be installed. After every 
add/update/upgrade of any of these dkms modules a restart of the webcamstudio 
service is needed, but that shouldn't be done auto by any of the dkms modules, 
since the user may want to use just them and not the webcamstudio application, 
thus resulting into install error of the dkms module(I will refine this auto 
service restart in later releases).

We've been thinking of removing this warning message, but this way the user may 
not be aware he is not having any of the dkms modules available and loaded. 

Maybe we need to think on another solution.

Anyway for now (even in SVN code) after installing/updating any of the dkms 
modules that work with WCS either manual restart of the webcamstudio service or 
a PC reboot is needed, so the changes could take effect.

Feel free to share any other convenient solution :)

Again... I am sorry for the annoyance....
