PS:
In a terminal window, you can log in as root by the command "su".  Unlike
"sudo", this command requires the root password, not the user password.

Or you can perform the ">" redirection also with sudo (with the user
password) in the following way:
sudo sh -c 'echo 7 > /sys/module/firewire_ohci/parameters/debug'

After that, "cat /sys/module/firewire_ohci/parameters/debug" should
confirm that there is a 7 in there now.  You can later echo a 0 into the
parameter in order to switch debug logging off again.

The above only works if sudo is configured rather liberally on your system.

Or you can do the following instead:
  1. Unload the controller driver with
     sudo modprobe -r firewire-ohci
  2. Check that it really went away.
     lsmod | grep fire
     (should not show firewire_ohci anymore)
  3. Load it again but with debug logging enabled.
     sudo modprobe firewire-ohci debug=7
  4. After you tested the camcorder and gathered the debug log, you get
     rid of the noisy driver by unloading it again.
