Query: I got a DKU-2, I wanted a DKU-5

I assumed that I would get a DKU-5, which is supposed to work according to the Nokia site. However, I got a DKU-2, which does indeed connect to my phone (6016i) but is recognized by neither Win XP nor Linux.I'm bummed... The part number should have been properly displayed somewhere. The packaging indicates that it is in fact Nokia part.
