I even tried to uninstall everything under Universal Serial Bus controllers. Tried to install previous version of bluetooth drivers. Tried to uninstall everything under Bluetooth. Plugged it back, the error appeared again.so basically, it was the bluetooth. 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. Buy it.I recently bought a Gigabyte GC-WB867D-I rev4.2. I was expecting to be taking it on and off everytime i moved my rig but the thing just stays there now looking like some hot shot CEO racing down the road in his drop top red ferrari a good magnet as wellĤ) the best part, and what made me write this review, is that i can lay the antenna flat, and stick in on the side of my case!!! makes it look like my case is wearing some super weird looking bluetooth earpiece. I love it, was worried about having and external antenna but lemme tell you, this bad boy does not dissapoint.ġ) It does not feel cheap, in fact it seems to be built rather nicely.Ģ) the antenna part swivels!!! it goes from laying flat, to a 90 degree upright stance, back down to laying flat on the other side.ģ) the base is magnetic.

Most people have covered the performance/install side of it.What I found to be the best part about it, something that no one touched on, is the ANTENNA!!!!!!!!!
