Plugable also gets in touch with you quickly. Pluggable sells you a solution, not an unsupported piece of junk like Best Buy. The difference is that Best Buy doesn't care about you once they get your money, and Plugable does. Since BCM20702A0 under Other Devices showed up when I first plugged the Plugable adapter in, it appears that both the Best Buy Insignia one and the Plugable one use the same chip. With their driver installed, the BCM20702A0 under 'Other Devices' disappeared and all the right things appeared under 'Bluetooth' in the Device Manager. They have a great website where they offer drivers that got me up and running in just a few minutes with no hiccups, other than it wasn't plug & play. They have motivated customer service people who will help you resolve problems. The solution: Buy the Plugable USB Bluetooth adapter from Amazon. I left that piece of garbage on the customer service counter at Best Buy when they refused to exchange it or provide any kind of support. When I needed to do a reinstall, Windows couldn't find the driver and both Broadcom and Best Buy washed their hands of it. I bought an Insignia Bluetooth usb adapter from Best Buy. The source of the problem is companies selling you garbage and refusing to support it. It installed, but nothing about Bluetooth appeared in the Device Manager and the BCM20702A0 device in the 'Other Devices' area still reported that it didn't have a driver. I tried the sp74543.exe driver with my bluetooth adapter and it didn't work. Business PCs, Workstations and Point of Sale Systems.
