Comment 0 for bug 1653274

I've tested my notebook with Ubuntu 16.04 (64-bit) LiveUSB pen drive and the mini-pci Qualcomm Atheros QCWB335 [168c:0036] properly works, both wifi and bluetooth.

After a fresh install from the same LiveUSB pen drive, the bluetooth do not work.

$ bluetooth
bluetooth = none (no device)

# lspci -nnvvv
