Laptop: xps13 9360 Distro: Manjaro Description: Bluetooth was working in linux413 and previous kernels, but after upgraded to 4.14 I found it not working and got the error message as following: # sudo journal -f | grep bluetooth Nov 20 15:49:33 KurikoArch bluetoothd[458]: Failed to set mode: Failed (0x03) Nov 20 15:49:57 KurikoArch bluetoothd[458]: Failed to set mode: Failed (0x03) Nov 20 15:52:10 KurikoArch bluetoothd[458]: Failed to set mode: Failed (0x03) in kernel 4.13, I can get the output: # dmesg | grep -i blue [ 2.658611] Bluetooth: Core ver 2.22 [ 2.658772] Bluetooth: HCI device and connection manager initialized [ 2.658776] Bluetooth: HCI socket layer initialized [ 2.658778] Bluetooth: L2CAP socket layer initialized [ 2.658783] Bluetooth: SCO socket layer initialized [ 2.709679] Bluetooth: HCI UART driver ver 2.3 [ 2.709681] Bluetooth: HCI UART protocol H4 registered [ 2.709681] Bluetooth: HCI UART protocol BCSP registered [ 2.709694] Bluetooth: HCI UART protocol LL registered [ 2.709694] Bluetooth: HCI UART protocol ATH3K registered [ 2.709695] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 2.709723] Bluetooth: HCI UART protocol Intel registered [ 2.709734] Bluetooth: HCI UART protocol Broadcom registered [ 2.709735] Bluetooth: HCI UART protocol QCA registered [ 2.709735] Bluetooth: HCI UART protocol AG6XX registered [ 2.709736] Bluetooth: HCI UART protocol Marvell registered [ 3.132455] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 3.132457] Bluetooth: BNEP filters: protocol multicast [ 3.132460] Bluetooth: BNEP socket layer initialized [ 7.648786] Bluetooth: RFCOMM TTY layer initialized [ 7.648792] Bluetooth: RFCOMM socket layer initialized [ 7.648797] Bluetooth: RFCOMM ver 1.11 [ 33.549141] Bluetooth: HIDP (Human Interface Emulation) ver 1.2 [ 33.549145] Bluetooth: HIDP socket layer initialized [ 33.551621] input: Microsoft Sculpt Comfort Mouse as /devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0/bluetooth/hci0/hci0:1/0005:045E:07A2.0002/input/input26 [ 33.551697] hid-generic 0005:045E:07A2.0002: input,hidraw1: BLUETOOTH HID v1.29 Mouse [Microsoft Sculpt Comfort Mouse] on 9c:b6:d0:d7:e5:7c but in kernel 4.14, I got the output: [ 2.810571] Bluetooth: Core ver 2.22 [ 2.810590] Bluetooth: HCI device and connection manager initialized [ 2.810593] Bluetooth: HCI socket layer initialized [ 2.810595] Bluetooth: L2CAP socket layer initialized [ 2.810599] Bluetooth: SCO socket layer initialized [ 2.834785] Bluetooth: HCI UART driver ver 2.3 [ 2.834787] Bluetooth: HCI UART protocol H4 registered [ 2.834788] Bluetooth: HCI UART protocol BCSP registered [ 2.834801] Bluetooth: HCI UART protocol LL registered [ 2.834801] Bluetooth: HCI UART protocol ATH3K registered [ 2.834802] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 2.834830] Bluetooth: HCI UART protocol Intel registered [ 2.834850] Bluetooth: HCI UART protocol Broadcom registered [ 2.834851] Bluetooth: HCI UART protocol QCA registered [ 2.834851] Bluetooth: HCI UART protocol AG6XX registered [ 2.834852] Bluetooth: HCI UART protocol Marvell registered [ 3.314487] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 3.314489] Bluetooth: BNEP filters: protocol multicast [ 3.314492] Bluetooth: BNEP socket layer initialized [ 8.215415] Bluetooth: RFCOMM TTY layer initialized [ 8.215421] Bluetooth: RFCOMM socket layer initialized [ 8.215426] Bluetooth: RFCOMM ver 1.11 [ 30.380104] Bluetooth: hci0 urb ffff9ecd3597fb40 failed to resubmit (113) [ 40.403292] Bluetooth: hci0 urb ffff9ecd4fd2b3c0 failed to resubmit (113) [ 64.509640] Bluetooth: hci0 urb ffff9ecd55ed6d80 failed to resubmit (113) [ 197.441281] Bluetooth: hci0 urb ffff9ecdb460bd80 failed to resubmit (113)
I have the same issue in arch stable kernel, apparently it's an issue with TLP, removing TLP works for me. https://github.com/lwfinger/rtlwifi_new/issues/116#issuecomment-298402908
and apparently it's a known issue with usb bluetooth devices in TLP, applied USB_BLACKLIST_BTUSB=1 to the tlp configuration as mentioned in http://linrunner.de/en/tlp/docs/tlp-faq.html#btusb and now it works with tlp enabled. so it seems power management in btusb changed somehow in 4.14 and it breaks this device?
for the record, my bluetooth device is from the Dell XPS 15 9560: lsusb line: 0cf3:e300 Qualcomm Atheros Communications
This has also been observed in Fedora[0] starting with v4.13.15 - it looks like the problem was introduced by https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fd865802c66bc451dc515ed89360f84376ce1a56 which was included in v4.4.100 and v4.9.64 as well.

Same problem on Arch Linux after upgrade(4.13.12-1 -> 4.14-2): https://bugs.archlinux.org/task/57286 Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 30) 0cf3:e360 Qualcomm Atheros Communications More logs and hw-info: https://gist.github.com/hxss/ebe0b535a4d57cd25b0eae4b7afa9d44
The QCA9377 is working in archlinux's kernel version 5.11.12.arch1-1, but the performance is severely degraded. The computer has to be located right next to the bluetooth device for the signal to reach. There is no problem in windows.
