Hi,

i'll ask them, but can't I figure this out somehow manually?
(could probably be faster... ? )

Receive failed: Broken pipe

So, I don't understand this, but to me this looks very unusefull :-(
because there aren't any outputs after the last command "Read Local Name"
the last line takes VERY long ("Receive failed"). I nearly hadn't have  
seen it.

But, accidently I found something that is perhaps more wicked.
After a reboot everything works fine:
"hciconfig -a"
"hcitool scan"
but after I put hci0 down manually, I can't get it up again :-(


root@viper root# hciconfig hci0 down
root@viper root# hciconfig hci0 up
Can't init device hci0. Connection timed out(110)

Well, thats bad because this definitly works with the zeevo chip.
I just rechecked that.
