Hi everyone!


I own a Belkin F8T001 as a Bluetooth device (=>I installed the related 
firmware), but I get an error during the rfcomm connect command

here is my procedure (since only yesterdy I began playing with it, perhaps 
there is a previous error I make)

1) bluefw usb 001/00X
2) modprobe l2cap
3) modprobe rfcomm
4) mknod /dev/rfcomm0 c 216 0
5) hciconfig hci0 up
6) hciconfig
7) hcitool scan
8) l2ping 00:01:E3:06:FB:AF
9) added the following lines to /etc/bluetooth/rfcomm.conf:

rfcomm0 {
  bind yes;
  # Bluetooth address of the device
  device 00:01:E3:06:FB:AF;
  # RFCOMM channel for the connection
  channel 0;
  # Description of the connection
  comment "S55";
 }
10) rfcomm connect rfcomm0 00:01:E3:06:FB:AF

Everything has worked perfectly till now, but this last command returns "Can't 
connect RFCOMM socket: Resource temporarily unavailable" or "Can't connect 
RFCOMM socket: Function not implemented"

only during the latest command, I launched hcidump -X to get more info of what 
was going on (but I can't decode it's meaning alas):
