wow, some ppl.... this is alpha stage USB hostmode, it is not a simple plug-n-play USB HM like N8. it is in extras-devel, so it may very well make your N900 burst into flames. dont know much about linux/computers? then leave it alone. too many ppl who dont know nearly enough about what they are messing with make it hard for developers and ppl who do know their sh*t to develop this sh*t !! sorry but it had to be said ..!
