I recently acquired a Bluetooth headset (Philips SHB9100) for my smartphone, but also wanted to use it with my Windows 7 PC, so I bought a cheap USB Bluetooth adapter without noticing it was a v2.0 adapter, while the headset is v2.1 + EDR.
The USB Adapter installed correctly on Windows 7, and I am able to discover my headset, but when they try to pair, an ugly Error 0x80004005 appears, never asking me for a PIN.
After some googling, and founding many people had this pairing problem, I read that the major improvement in Bluetooth v2.1 is SSP, which permits pairing without the need to enter a PIN, and also that Windows 7 chooses the "best pairing mechanism" automatically. And so I started to suspect that this is what's happening:
- Windows discovers a SSP capable device.
- Windows tries to pair with that device using SSP.
- The USB Adapter, being v2.0, is unable to permit pairing with the headset via SSP.
- Windows does it's best showing a 0x80004005 error.
I searched for a v2.1 or superior USB Bluetooth Adapter in my city but couldn't find any (I'm from La Plata, Argentina) and even though I think I'll end buying one, I'd like to make this work, or at least know for sure why the devices aren't pairing.
And so my question is (and I swear I did some more googling before asking here): Can I force Windows to try a legacy pairing with my headset?
Any info on the subject is welcome. Thanks!
