udev persistance promblems

[Erez D]

I have a strange problem

when i insert my wlan usb dongle, I get wlan0.
if i remove and reinsert, i get wlan1
next time - wlan2
etc..

if i look at /etc/udev/rules.d/*Persistance*
i see multiple lines that are completely identical, except the wlan number

any idea ?
any idea of how to debug this ?
