I am trying to use a bluetooth USB, but Ubuntu 12.04.01 does not identify it. How to make external USB bluetooth dongle work with Ubuntu 12.04.01.

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