Here's a quick and dirty workaround: after you delete the uvcdynctrl-udev.log file, create a symbolic link to /dev/null so that new text is thrown out.
sudo ln -s /dev/null /var/log/uvcdynctrl-udev.log
I haven't experienced the high CPU usage that others have reported, so I don't know if this has any effect on that or not.
