If you are either a user or a developer you can trace akvcam using dmesg.
First at all, if you have the driver already loaded, unload with rmmod akvcam.
Then clean the old dmesg buffer with sudo dmesg -C and then you can print an interactive log with dmesg -w, or you can save the log to a file with dmesg -w > akvcam_log.txt.
Now, in a new terminal, you can reload the driver with:

sudo modprobe akvcam loglevel=7

or from the sources folder with:

cd akvcam/src
sudo insmod akvcam.ko loglevel=7

Finally, use the virtual cameras as normal.
