Recently picked up an IOGear GBU521 Bluetooth 4 USB adapter for the sole purpose of getting a Magic Trackpad, which is my preferred input device, working wirelessly. Though it is supposed to be plug-and-play, I wasn't able to get it working--I suspect that it may be because of the fact that the device is plugged into USB3 ports. Unfortunately, this particular board doesn't have anything BUT USB3 ports, so I can't move it to a USB2 port.
Anyway, it's perfectly recognized:...
USB Dongle recognized but non-functional
