Bluetooth Dongle installation problem in Windows 7

Hi - I have 2 laptops one (First one) with Windows 7 upgraded from Vista and the other (Second One) Windows 7 clean install.

I recently got a Bluetooth Dongle (USB 2.0 MINI BLUETOOTH V2.0 EDR DONGLE - a.k.a CSR Bluetooth USB dongle) and tried on both the laptops. Here is my problem - On the first computer (Vista upgraded to Win7) it installs as CSR Bluetooth Device under device manager (driver file is btcusb.sys) and it does not work at all. Cannot find bluetooth devices nor devices could find by computer.

On the second computer (win7 clean install NOT an upgrade) it installs as Bluetooth Radios [ Generic Bluetooth Radio & Microsoft Bluetooth Emulator - driver files are bthport.sys, BTHUSB.SYS, fsquirt.exe & bthenum.sys ] and everything works fine.

What could be the problem in my first computer that stops it from installing the same way as it did on the second and what all things I could do to fix it - Thanks you in advance.

After much struggle I figured out (thanks to another thread for clues) how to force install the generic BT drivers. Go to device manager - bluetooth - right click - update driver - choose from my hard drive - chick List the available drivers in my drive - choose Generic BT drivers .

It works the same way on my first laptop that is a Vista upgrade to Win 7

Thanks you all who might have looked into it -

Three years down the line, such simple solution fixed this problem for me too. Thank you so much!

8 years down the line this simple step worked for me as well!

This is after going through a lot of frustration and bought and returned 2 bluetooth adapters. I followed the instructions and installed the Generic Bluetooth Radio driver and it worked immediately. $10 bluetooth adapter vs having to buy a new PC. Thank you!
