This is a handy little Bluetooth USB mini-adapter. This adapter supports Bluetooth v2.0 class 1 and has a maximum distance of up to 100m. The adapter also includes an indicator LED. Great for laptops and if you're on the go!
This device does not include any drivers or software, however, you shouldn't need any as it supports the native Windows Bluetooth stack (Windows XP, Vista, 7). Plug it in and Windows should handle the rest.
Of course, we couldn't resist taking it apart.
Please note: Many of these modules have been found to have the same Bluetooth address. If you're simply trying to connect from your computer to a cell phone or headset, these will work great. If you're attempting to attach multiple modules to a computer, the computer will not be able to address both modules at the same time.
