Tried to unplug the bluetooth usb cable from the usb2.0 motherboard header (MSI Z97 Gaming 5), and the unknown usb error disappered. I also noticed that I get Unknown USD Device under Universal Serial Bus controllers. Upon, checking the properties, I get code error 45. I selected View>Show hidden devices, and the bluetooth appeared but was all greyed out.

I checked device manager and 'bluetooth' was not listed anymore. I downloaded the latest drivers from Intel, installed, restarted, still nothing. Checked windows settings and there was no option to configure my bluetooth on/off. Then after a month or so, when I wanted to send something via bluetooth, my bluetooth icon in the task/tool/notification bar disappeared. I tested WiFi and and Bluetooth sending and receiving. I downloaded the latest Intel drivers for it (AC8260 for AC Wifi and Bluetooth drivers) and got the thing to work.
