All the hotplug stuff are simple shell scripts, so you can put in
"echo" statements as much as you please.  To circumvent any potential
issues with syslog etc., I'd recommend doing it so
   echo "hello I'm here" >> /tmp/mylog

This will put the stuff in /tmp/mylog, which is the most direct
way you'll get debugging info out of the script.

Make a backup copy before changing any script, and then hack
away until you find out the control flow in your specific
case.  And where it fails the firmware loading.
