Jasem, the rule  you´ve added does not work on my system (Tumbleweed):

edgar@Edgar-Desktop:~> cat /sys/module/usbcore/parameters/usbfs_memory_mb 16

Looks like cat /sys/module/usbcore/parameters/usbfs_memory_mb has to be set into "back apostrophes" (don´t know theright word in english :)

This is working for me:
ACTION=="add", SUBSYSTEM=="usb", RUN+="/bin/sh -c 'test -f /sys/module/usbcore/parameters/usbfs_memory_mb && test `cat /sys/module/usbcore/parameters/usbfs_memory_mb` -lt 256 && echo 256 > /sys/module/usbcore/parameters/usbfs_memory_mb'"
