normally I use linux on it; starting XP by the linux bootmanager.
Tunerpro works well, but the ostrich wasn't recognized.

after searching in www, I found a tip for using a game console, this needed a FT232R USB driver.
I installed this, and ... it works now

you can find the driver at

may help someone...

with best regards
