You can pullout and disconnect the usb-bluetooth device(from usb-port) and connect
again,
see the messages.
Do you get anything on /proc/bus/usb/devices?
(hope the proc filesystem is mounted)
Device open fails, when there is no device registered with that name.

registered
Sep 2 11:14:20 Bluetooth-Host2 kernel: usb.c: registered new driver
bluetooth
Sep 2 11:14:20 Bluetooth-Host2 kernel: bluetooth.c: USB Bluetooth tty
driver v0.12
2.--
Now if I add bluetooth(ROK) module its- not givining any message. why?
3.--
and /usr/src/linux/Documentation/usb/bluetooth.txt saying that device name
be /dev/ttyUB[0-255]. Why its failing open the /dev/ttyUB0, not
