Bluetooth not working with xHCI (USB 3.0) on Intel 7260 chipset in Asus UX301LA
Solution 1:
I solved this problem on my Asus Zenbook UX301L by replacing the Intel 7260 wifi/BT adaptor with an Intel 7265 wifi/BT adaptor. The problem immediately vanished. The only problem was getting the back off the UX301L. Not easy.
