As I understand it, this is less than trivial. For example, say you have two usb sticks. if you swap them to different ports can you really expect udev to still be able to identify them uniqely? Many devices have no way of doing this that is consistent. If you attempt to create a method to implement this, it very quickly becomes a messy black art type situation, where guesswork is as useful as good programming.
In the case of USB sticks, it's trivial for a couple of reasons: First of all, all USB devices have a unique serial number. This means you can canonically identify a particular USB stick, regardless of filesystem, and create a udev rule to mount it or name it something. Secondly, the filesystem within the device will have a GUID, which can be used to identify that particular filesystem. If you format the filesystem the GUID will change, but assuming that doesn't happen, you can still write a udev rule to specify where to mount the device. Unfortunately you picked a bad example :)
