thanks, It works now.

But i found other problem.

When I make "hciconfig hci0 up"
Interface goes up.
next "hciconfig hci0 down".
Interface goes down.
next hciconfig hci0 up"
I get this error:
Can't init device hci0. Connection timed out(110)

I must reinsert dongle or rmmod/modprobe kernel module hci_usb.

Best regards,

Pavel Ruzicka

this problem only occurs on UHCI USB host contollers. The USB guys have
a bunch of fixes and I hope this gets fixed some time.
