Indeed, the module doesn't load twice. My problem is that it hangs
around after my application is closed, so if I launch a new instance of
the same application fast enough it enumerates the previously created
echo cancel devices and the user could choose those to work with.
Anyways, I solved the problem by not displaying the devices that have
the owner_module set to "module-echo-cancel". So thanks again for your
help!
