Side track (Pairing Plantronic Backbeat go and Jawbone/Jambox in Windows 7)

This passage is written in English because this info may be useful to non-Chinese reader.

I have spent days trying to pair the Bluetooth headphones and speaker with my PC. However, although pairing successfully, the devices was not functioning because Windows cannot find drivers for the new devices. I have checked the Plantronic and Jawbone official sites and there are no drivers to download. The fact that I have been using these devices with no problem with my Macbook and Andriod Tab lead me to suspect that the problem may be the Win7 bluetooth driver.
The bluetooth receiver I am using is a generic one and the driver is therefore a generic bluetooth driver. Yet, a generic driver may not be capabable to employ all the functionalities of the device just as your NVidia GTX650 card will only work like a cheap VGA card with a generic driver. So, I have to determine the exact driver I should use. From the device ID, I noticed my bluetooth receiver is made of Cambridge chipset. But there are so many manufacturers using this chipset with their own specific designs. Which is the correct one? I used the driver scan software from DriverZone (www.driverzone.com) to determine that. Registeration is free. And in a few minutes, the software found that mine is a variation of Asus bluetooth and downloaded the correct driver. Installed the new driver, re-boot, and everything is running perfectly now.
** It appears that driverzone is not free anymore and for some reason.
