Christopher M. Penalver, sorry for the delay. I've booted liveUSB and installed the last three Ubuntu LTS (12.04.5, 14.04.5 and 16.04.1) and all of them have the exactly same behaviour. When booted from the LiveUSB, both WiFi and BLuetooth works like a charm, but when booted after a fresh install, Wifi works and bluetooth is not detected (no device installed), and in all the cases, after a system "Suspend", Bluetooth is detected again.
I don't know what's the source of this problem but I'm quite sure that this is not a simply regression on a kernel version. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1653274 Title: [HP ProBook 4540s] Qualcomm Atheros bluetooth properly works with Ubuntu 16.04 LiveUSB but not on a fresh install Status in linux package in Ubuntu: Incomplete Bug description: I've tested my notebook with Ubuntu 16.04/17.04 (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 does not work. $ bluetooth bluetooth = none (no device) Pressing the WiFi button turns off WiFi, and does not enable bluetooth. Pressing it again turns WiFi on, but bluetooth remains off. WORKAROUND: Suspend, and unsuspend the laptop.
