I should note that this started right around when kernel 3.11 came into play. 
Not exactly at that point but 3.10 worked fine. I'm guessing it's a change in 
the kernel but I haven't had time to check out the changes to see where the 
problem is.

Exactly the same problem (both with webcamstudio-dkms and v4l2loopback-dkms - 
not sure if I should have both installed but problem was present before I 
installed v4l2loopback)

~$ sudo modprobe v4l2loopback
ERROR: could not insert 'v4l2loopback': Bad address
~$ sudo modprobe webcamstudio
ERROR: could not insert 'webcamstudio': Bad address
~$ webcamstudio
None of the kernel modules webcamstudio/v4l2loopback are loaded...

I try to build 32bits Ubuntu 13.10 deb packages and this is the results:

https://docs.google.com/file/d/0BxkZ_wh6t7jbemljTjVWeEN0a2c/edit?usp=sharing

Please, don't try this in production machines.

1) Uninstall all previusly WS installed version from synaptic
2) make sure module webcamstudio is not loaded, if it is loaded (but not 
functional) reboot the system and go back to step 1.
3) Download the attached package, you will find two debs:
     a) webcamstudio-dkms_0.64_all.deb
     b) webcamstudio_0.64_i386.deb
4) Install a) with dpkg or Software-Center
5) Install b) with dpkg or Software-Center
6) Restart the system.
7) Check WS installation.

You can also try to compile this webcamstudio-module-108:

Let me know.

Ubuntu 13.10 Saucy PPA created with correct WCStudio video module.

• Changed state: Fixed

This isn't closed for me. I don't see any changes in the behavior and the svn 
doesn't show any changes to vloopback module

webcamstudio-module108 contains the Linux 3.11 fix of v4l2loopback module fork.
The latest saucy repo have that.
This issue is closed.

V4l2loopback doesn't seem to be fixed.  I still get the same error of "bad 
address".

The V4l2loopback install problem was fixed about 6 days ago on the latest 
source on github.  Nevermind.  Not in the Saucy repositories yet...

I see that webcamstudio-module-108 has already the correct "depmod -a" in 
makefile.
Thanks.
