USB Bluetooth is a small device like the flash drive that is being connected into your computer or laptop via its USB port to enable file transfer. It is commonly used in transferring files from mobile phones which is Bluetooth enabled to your PC. You simply plug it in the USB port and wait for the computer's response. The computer will detect its drivers and installs it. Yeah, it is automatic because for most of the USB bluetooth has built-in drivers. Though, in some cases you need to download it from other sources. After the installation, in my case I'm using the Windows XP flatform, I can see a Bluetooth icon in the icon tray, that is in the the lower right corner of the screen. If you want to use the Bluetooth just right-click the icon and it will give some options either to send or receive and some other things. The succeeding steps is just a matter of click. It is easy to understand.
