Ignoring the device still makes it "active" in the system, especially as you just tested that the usb-storage device was bound to your device (which wouldn't be true that early in the process, which is one reason why this failed). you need to write a 0 to the "authorized" file in sysfs which will disable the whole USB device entirely if it meets your "list of devices to reject". You also need to test not for driver binding, which again will not have happened, and you don't want to have happen, but that it is a usb storage device type (by virtue of the correct class config options as shown by sysfs) and that it doesn't pass your list of valid serial numbers. Note, all of that might be easier to do in a script than in a udev rule alone, but it should be possible.
