Cool, Just try your patch over here and it seems to work!! I have a few patches also for submittal and if we can get more people to test your patch I will be happy to see that the latest driver gets committed. The latest driver should be always available from : http://www.freebsd.org/~ahasty/Bt848.html or from ftp://rah.star-gate.com/pub/bt848.tar.gz Tnks!
