Ubuntu does not identify the external USB bluetooth. – Gaurav Agarwal Mar 11 '13 at 12:15
There the problem comes . what branded bluetooth it is ? – Raja Mar 11 '13 at 12:17
I checked the package it is Tech-Com SSD-BT-819 and it is working fine on Windows 7. I am noob to Ubunu making transition from windows to Linux. – Gaurav Agarwal Mar 11 '13 at 12:22
Please post the results of lsusb as @Jai asked ;) See… for pointers (you need to find the hardware ID before anyone can help). – Rinzwind Mar 11 '13 at 12:29

You might want to try

add "blacklist hci_usb" to /etc/modprobe.d/blacklist.conf, and add "hci_usb reset=1" to /etc/modules

I tried it does not work. – Gaurav Agarwal Mar 16 '13 at 18:15

another idea if this fails is to look for a suitable firmware and update the firmware of your dongle via dfutool. I just mentioned this as an annotation, haven't had problems with bluetooth devices myself.
