udev rules not working properly


I am facing problem with udev. The udev rules has following rules.

# wifi dongle
ACTION=="add", SYSFS{idVendor}=="07d1", SYSFS{idProduct}=="3c11", RUN+="/etc/udev/rules.d/"
ACTION=="add", SYSFS{idVendor}=="148f", SYSFS{idProduct}=="3571", RUN+="/etc/udev/rules.d/"
ACTION=="remove", SYSFS{idVendor}=="07d1", SYSFS{idProduct}=="3c11", RUN+="/etc/udev/rules.d/"
ACTION=="remove", SYSFS{idVendor}=="148f", SYSFS{idProduct}=="3571", RUN+="/etc/udev/rules.d/"

This rules is been followed while I insert wifi dongle. I mean when I insert is called and I can insmod my driver ko.
But when I remove wifi dongle is not called at all. And I can't rmmod driver ko.

Can you suggest why this is happening.

Answering because nobody else has rather than because I know much ...

udev logging may provide clues. It can be set by udevadm control --log-priority=value where value is one of err, info and debug. Debug is very verbose so it may be better to try info first. The messages end up in one or more of the /var/log/* files, perhaps debug, messages and/or syslog.
