Windows 7 not detection any bluetooth peripherals.  

I have searched dozens of forums post even remotely pertaining to this issue but the solutions posted never fix my issue.

So here is the story and I will be honest cause I'm pretty sure my problem is of my own making. Bought sony DRBTN200 bluetooth headphones for my sony xperia V ultra and decided they would work great with my pc too. Bought an IOgear gbu521w6 usb bluetooth dongal. Installed dongal with newest drivers from IOgear website. Everything installed properly but was not able to add my headphones in Hardware and Sound> Devices and Printers> add device, or add bluetooth device. "Add Device" window opens but just sits at "Searching for Devices.... Make sure your device is discoverable". It is at this point that I make my mistake but we will come back to that. So I try the usual fixes. Uninstall/reinstall everything and try again. Still same thing. So it try a different tack.

My phone has bluetooth lets try it. Windows and my phone do their thing. Check the PIN numbers everythings good all that stuff and they connect. So figure it an issue between the headphones and dongal and pc communicating. Dig dig dig. Update this. Try that. Make sure Bluetooth services are started. Post says change this setting to that. Other says change this one. Hours go by. Neither phone or headset are seen by Windows 7. Headset and phone working great together. Phone still sees PC bluetooth. Try to pair. No PIN comes up on Windows 7 machine.

Go buy brand new dongal. Rockfish RFMRBTAD model. Do all step to install. Same thing. Since Windows is not seeing either Sony product phone or headset contact sony and here is where we get back to my mistake. While troubleshooting with Sony. Learn proper way to make headphones discoverable to non-sony devices. So I am pretty sure I messed up some part of the Bluetooth services after I was able to connect my phone that is preventing Windows from properly looking for and seeing Bluetooth devices.

I did do a system restore if you were asking but it was after my mistake. My install cd and everything are with my soon to be ex-wife. So I kind of need a way to reset windows 7 bluetooth services back to what they were before I started all this. Both Bluetooth service and Bluetooth Support service are running but I seem to have corrupted or broken them. So if anyone knows how to fix this props ahead of time. Thanks

Yeah not a protocol issue checked that.

Let's try going back to square one

1. /* EDIT */ Step1 is remove any USB dongles
2. Open CtlPnl->Programs and Features. Look at EVERY entry. Uninstall anything you may have installed for your BT dongles
3. Download and run either the 32- bit DevManView or the 64 bit version of DevManView (based on if you're running 32- or 64-bit Windows
4. Run DevManView. Click Ctl-F and search for the word Blue. For each Bluetooth entry you find, click File->Uninstall Selected Devices. (I'd expect you to have several entries including BT enumerators, radios, networks and maybe more)

Under Administrative Tools->Services... you should only see one bluetooth service named Blue Tooth Support Service. Do you see more then one Bluetooth service?

Reconnect your USB dongle. Look at Devices and Printers. You should see a Bluetooth device (probably Bluetooth Radio) listed. Right click->Settings. Make sure both boxes under Connections are checked

Allow your device to be discovered. First question: Can your PC find the device?
/* EDIT */
I just looked at Sony support for your headset. It seems they don't warrant it to work with anything other then Windows 8!! Arghhh http://esupport.sony.com/US/perl/sup...0&mdl=DRBTN200
