https://bugzilla.kernel.org/show_bug.cgi?id=97741 Bug ID: 97741 Summary: hid-logitech-dj drops connection after idle period Product: Drivers Version: 2.5 Kernel Version: 3.16.0-33 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: monochromec@xxxxxxxxx Regression: No This bug surfaced when I tried to connect a Logitech K400r keyboard to an Athlon(tm) II X2 245e based system running kernel 3.13.0-51 (64 bit). I was able to reproduce the same issue on 64 bit kernels 3.16.0-33, 3.16.0-34 and 4.0.1-1 (all Ubuntu versions apart from the last which is Arch running on an Atom N540). Symptoms are as follows: kernel accepts key presses from the keyboard but stops after a while. Bluetooth status of the device is then "offline" as reported by "solaar-cli show" which is using HIDAPI internally via Python. Double-checked that autosuspend in usbcore is disabled. Let me know if you need more details. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
