Thank you for the reply, however I am very confused by your post. I am using Ubuntu 8.04, and by the sounds of it your using some distro with KDE because to the best of my knowledge ubuntu 8.04 does not have a 'kmenu'. However if I am wrong please please let me know.
This is they I found the type and name for my Asus WL-167G usb adapter, keep in mind that I forgot some of the steps.
Go to Kmenu > Radio Network Analysis > 80211 > Analyzer > Kismet
This should give you a different output, be fast when Kismet starts it will list the Interface, Chipset, and Driver.
By the way are sure your adapter is capable of packet injection?
