ATHEROS AR5B22 Dual Band Laptop mini pcie wireless card 300Mbps and Bluetooth BT4.0 combo card

Physically and electrically, this fits in my HP PAVILLION DDE7-7xxx system.But it won't install, and after a couple of hours' research I determined that there don't appear to be any compatible drivers for HP systems. In fact, I couldn't find a generic driver that was compatible with it on any hardware.Didn't bother to return it because it cost almost nothing. But that's exactly what it's worth to me...

fits my Chrome book and works fine

Prompt delivery and item is working perfectly.

I tried this card in two different laptops (different brands) with Windows 10 Pro, and never could get the bluetooth to work properly, even after trying out numerous drivers. I couldn't use it.
