My udev is, indeed, too old (version 117), so I implemented a similar technique:
SUBSYSTEMS=="usb", ACTION=="add", SYSFS{idVendor}=="06e0",
SYSFS{idProduct}=="f111", ENV{REMOVE_CMD}="/usr/bin/logger GOODBYE"
ACTION=="remove", ENV{REMOVE_CMD}!="", RUN+="$env{REMOVE_CMD}"
That seems to be working. The problem I'm encountering now is that it
seems there are several "remove" actions called during initialization
of the device. If I swap in the "modprobe -r" command described in an
earlier email, it unloads the driver for the device before it even
finishes initializing.
Below I've attached a sample syslog snippet showing the many "GOODBYE"
messages logged when I plug in the deivce. Also I've attached the
output of "udevmonitor --env". For good measure, I've also thrown the
output of "udevinfo -a -n /dev/ttyUSB0" at the end.
Any idea how I can get my RUN command to only execute when I'm
actually unplugging the device?
Thanks!

# udevinfo -a -n /dev/ttyUSB0
Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
