• go to device manager (run->devmgmt.msc) & right click on the "usb device" that would be written in yellow color then click on properties. 
• Now click on the "Details" tab.
• You will see a drop-down list box, from the box select "Hardware Ids"in the below box you will see 2 different hardware ids.Click on the last hardware id & press Ctrl+C to copy the hardware id. 
• Now goto run & type "c:\windows\inf\bth.inf"(without quotes) 
              
• a notepad file will appear, scroll down a bit till you find different manufactures name in square brackets[ ]. below will be the model name and number of the Bluetooth that windows in-built driver supports.
• Now under any manufacture’s name type the name you want to give to your Bluetooth device.After that out "=" and then type "BthUsb," then put a space and then paste the hardware id.

Example : I want my Bluetooth name to be "AKS-Feel The Change!"
                so i will write :
                AKS-Feel The Change=BthUsb, "hardware id"
                lets say this way:
                AKS-Feel The Change=BthUsb,USB\Vid_1caa&Pid_0001      

• Now save the file. vista users must give rights to the bth.inf file before saving the file or it won’t save.
• Now go to the Bluetooth properties from where you copied the hardware id and go to the driver file.
• Click re-install driver or update driver.
• let windows search the driver automatically.

• Now windows will treat the USB device as compatible which has in-built driver support.

       Now your Bluetooth Dongle work perfectly.

Now, the question is how to access it?

Here’s the answer go to run –> type “fsquirt” (without quotes)
