kismet and SanDisk WLAN Card

[deniscallies]

Hello,

last night i tried kismet on my C 700 on Kathrin RC3
I found a compatibility- List which says my SanDisk WLAN Card has a Prism chip.
edited the kismet.conf to prism, but kismet says

Unknown capture source type ´prism2´ in source ´prism2,eth0,prism2source´

so, what do I have to write into my kismet.conf?

thanks  Denis
