When I execute hciattach I get following message:

root@arm:~# hciattach /dev/ttyO5 bcsp
Device setup complete
Bluetooth: Out-of-order packet arrived, got 1 expected 0

Is there any real tutorial for this chip? I found some related
threads, but would like to see the picture in whole or to get some
tips on how to debug my issue.
