different wireless devices with same disk image
I have a slackware-14.1 arm image I can successfully clone onto sd cards to run slackware arm on two different raspberrypi's. However, I can only use the wireless usb device which was configured to provide wireless on the original system (wlan0). Using the exact same model dongle (Asus WL167G, which of course would have a different mac address) results in a new device (wlan1) which I can not configure to connect to my lan.
Is there a way to remove the history (don't know what else to call it) of the original wireless device? remove reinstall package(s), delete contents of some file? This seems to be a little deeper than the wicd configuration.
