Possible regression from this commit: commit c9829dd3f00809ccf10afeb904ba5c53c3c3d6e7 Author: Takashi Iwai <[email protected]> Date: Thu Mar 15 17:02:34 2018 +0100 Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174 BugLink: http://bugs.launchpad.net/bugs/1764973 commit f44cb4b19ed40b655c2d422c9021ab2c2625adb6 upstream. The Atheros 1525/QCA6174 BT doesn't seem working properly on the recent kernels, as it tries to load a wrong firmware ar3k/AthrBT_0x00000200.dfu and it fails. This seems to have been a problem for some time, and the known workaround is to apply BTUSB_QCA_ROM quirk instead of BTUSB_ATH3012. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773635 Title: AR3012 Bluetooth not start after an upgrade to 4.4.0-127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1773635/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
