IŽve this issue with all kernel updates since May this year and in every version the hci0 device becomes suddenly unavailable due to lock in as it seems. I see for a couple seconds while shutting down the laptop an error message from hci0 saying the the device is unable to process something. But I had no luck to shot of this message neither IŽm able to find the message after a reboot in any of the logs.

I own three of them and the other two work on two different laptops. All of these laptop have the Intel Bluetooth module for a Skylake choose integrated. But only with the Acer I have issues. One of these laptops run fedora 24 with kernel 4.8 and latest bluez.l Ike tumbleweed. The other runs the 6.8 with kernel 2.36 and bluez 3 or 4.x.. No issues with them. Under tumbleweed the latest kernel was 4.2 where the mouse worked. Since 4.3 I have constantly this problem. I have found at the bluez site z page describing how to debug, but this requires as I understand the compilation of the driver itself. I didn't get it working. may be you have an idea how to debug the driver and enable and raise the logs to debug level to figure out when the module becomes issues with the input. I attached a fast hardware info file. Maybe this help you to find the exact hardware of the built-in Bluetooth device. Otherwise I will update later the issue with the output of lspci and lsusb.

Unfortunately I don't have such a device at hand, so I cannot test. Testing with three identical mice is not that interesting, it would be interesting with a different Type of USB mouse (I once had a Logitech MX1000(?) mouse which had an advanced power management feature, which was not well supported in bluez at that time, and whenever the mouse went to sleep, it would not reconnect again -- but this was a bug in bluez). But if it is "hci0 not responding", then it looks like either an USB host controller or btusb driver issue. I'm adding a USB expert to cc :-) Passing module parameters to btusb can be done via /etc/modprobe.* files, but even easier: just unload the module and reload it with the desired parameters: rmmod btusb modprobe btusb reset=1 (example). Which bluez debugging page are you referring to? Maybe I could build you a debug package, but I would need to know what to do exactly. -- You are receiving this mail because: You are on the CC list for the bug.

I have attached some info from hciconfig, bleutoothctl, dmesg, lspci, lsusb etc.. Its a single file containing all the output from the commands. The error message is found after executing hciconfig -a. Additionally I tried to reset btusb and for my surprise the mouse worked after laoding it again. Also I tried to reproduce this issue so that it is possible to track down what happens her. And I have a feeling that it mmostly happen together with Firefox. For explanation: IŽm booting up and start firefox. FF load then a bunch of tabs (hatze bookmarks) and after some seconds AND while FF loads pages the communication ends with a timeout in hci0. If IŽm let FF load all the pages, then it happens much later but mostly while IŽm entering some text and moving the mouse and clicking on buttons - nearly all actions are done within the same second. Also IŽve noticed that it happens with "responsive" webpoages, where FF are loading some content (AJAX like) for the page (single page design). DoesnŽt know if there is any correlation to bt. Thanks!

SO I think this is not related to the Logitech Mouse itself. IŽve also installed in parallel Win10 and experience no issues with both mice while running windows.
