My friend,

Yamahas' america homepage is useless to get the driver:furious: ,so you do this:
go to Yamahas' UK page (Google it) and there choose driver downloads
under that ,choose "PC hardware" and there you have two drivers WF1000XG and WF192XG

Waveforce XG192driver should do the trick :) for the chip you have as it have worked fine for me.

Best regards
