I was getting an error called "driver not found" for the below hardware id:
I have got myself a Trust Bluetooth USB adapter and on its official site i can only find the XP drivers which was not working on Vista. So, I searched on the net and finally found a BroadCom Bluetooth Software that I downloaded from this link - http://www.broadcom.com/products/bluetooth_update.php, but this did not work for me either. So i thought why not lets try and edit the btwavdt.inf in BTW_22.214.171.12400\win32 manually, so first i backed up the BTW_126.96.36.19900 folder and then in the WIDCOMM section I added the below line
After that I saved and closed this modified .inf file in the same folder as btwavdtmcsty.inf and guess what, it did actually work at the very first time. I saved this modified .inf file in the same folder as btwavdtmcsty.inf and it worked for me!Hope that it works for anybody who is having similar problem.
