Can you show me a picture ? What exactly did you do? (Can you send your 
patch - created with cvs diff -u if you are using dvb-kernel)

Can you point us to a picture of the Stick, please? I suppose it is a 
mt2060-based device, and there is no driver for this tuner yet. (Microtune 
does not want to have an OpenSource driver). (That would also explain why 
your card doesn't tune)

Are you sure about the MT352 (from Zarlink)? I highly doubt that, because 
if there is the DiB3000P then there is already a demodulator.
