Hi Bachus and Frans,
I think Bachus’s setup is the better way to go also.

Thanks Bachus.

They included the Bt 01 in my p121/ sx900 package, otherwise I doubt I would have bothered.

The powered USB hub sounds like a great option, heard it mentioned on Yamaha forum also, so good to know it does work.

Sheer laziness , haven’t gotten round to checking out powered USB hubs yet, didn’t actually know what they were referring too. Rather embarrassing .haha
