Every time bluetooth stops working silently, dmesg mentions: [ 8834.765143] usb 2-7: reset full-speed USB device number 7 using xhci_hcd Here's the log from one session where it started to misbehave quite often: (The bluetooth mouse is not the only BT device that are affected.

btmon.log
Experiencing the same issue as the original reporter. Attached is the result of the btmon.log command, where the error occurred ~1-3 seconds after the error occurred.
Other details: the issue started after I updated to Ubuntu 18.10 (didn't seem to be present in 18.04). There are complicating factors in my setup: I'm using an Intel 7260 PCIe WiFi/Bluetooth adapter which has pins 20 and 51 masked (the issue occurred with only pin 51 masked prior).

Can be marked as solved. I'm not sure when it was solved though. Everything started to work as intended after an update some time ago. If anyone hits this particular problem, please update your kernel to 4.18.20 or later. Just updated to 4.18.20, issue not resolved. Should I open a new issue? Created attachment 280073 [details] attachment-2422-0.html Yes, please do. :-) On Mon, 17 Dec 2018, 21:07 <bugzilla-daemon@bugzilla.kernel.org wrote: > https://bugzilla.kernel.org/show_bug.cgi?id=198303 > > --- Comment #9 from Nick (rishel.nick@gmail.com) --- > Just updated to 4.18.20, issue not resolved.

Created attachment 273335 [details] journalctl -b -u bluetooth.service Description: Bluetooth suddenly stops working after some (arbitrary?) time. Restarting the systemd service does not help. If one reload the btusb kernel module, one can resume the bluetooth functionality. This has to be repeated quite often during a session. Sometimes with only a few seconds between the failures. Other times it can go several hours without any failure. Additional info: Distribution: Arch Linux Kernel: linux-4.14.9-1 Additional packages: * systemd 236.0-2 * bluez 5.47-4 Steps to reproduce: 1. Boot normally. Enable and pair a bluetooth device. Use it as intended. 2. After some time (seems arbitrary), the bluetooth suddenly stops working. No messages about disconnection or anything. It just silently stops working. 3. "systemctl restart bluetooth.service" does not help. Generates errors as seen in the log attachment below 4. "rmmod btusb && modprobe btusb && systemctl restart bluetooth.service" helps to recover the bluetooth functionality.
