Hi, In trying to diagnose a problem with bluetooth-audio on my laptop, I've spotted that the firmware is failing to load. The bluetooth related output from dmesg is: [ 0.426890] Bluetooth: Core ver 2.19 [ 0.426986] Bluetooth: HCI device and connection manager initialized [ 0.427038] Bluetooth: HCI socket layer initialized [ 0.427087] Bluetooth: L2CAP socket layer initialized [ 0.427137] Bluetooth: SCO socket layer initialized [ 1.017575] Bluetooth: hci0: read Intel version: 3707100180012d0d00 [ 1.017602] bluetooth hci0: Direct firmware load for intel/ibt-hw-37.7.10-fw-1.80.1.2d.d.bseq failed with error -2 [ 1.017604] Bluetooth: hci0 failed to open Intel firmware file: intel/ibt-hw-37.7.10-fw-1.80.1.2d.d.bseq(-2) [ 1.017608] bluetooth hci0: Direct firmware load for intel/ibt-hw-37.7.bseq failed with error -2 [ 1.017609] Bluetooth: hci0 failed to open default Intel fw file: intel/ibt-hw-37.7.bseq [ 8.286733] Bluetooth: RFCOMM TTY layer initialized [ 8.288739] Bluetooth: RFCOMM socket layer initialized [ 8.290693] Bluetooth: RFCOMM ver 1.11 [ 63.965245] Bluetooth: HIDP (Human Interface Emulation) ver 1.2 [ 63.965257] Bluetooth: HIDP socket layer initialized [ 63.966748] input: Bluetooth Laser Mouse as /devices/pci0000:00/0000:00:14.0/usb1/1-7/1-7:1.0/bluetooth/hci0/hci0:256/0005:04B4:0033.0001/input/input10 [ 63.966891] hid-generic 0005:04B4:0033.0001: input: BLUETOOTH HID v6.11 Mouse [Bluetooth Laser Mouse] on 80:19:34:5a:67:51 The firmware two files mentioned are installed in /lib/firmware/intel and are successfully loaded by a 3.17.6 kernel: [chris:~]$ dmesg | grep -i blue [ 7.103619] Bluetooth: Core ver 2.19 [ 7.107523] Bluetooth: HCI device and connection manager initialized [ 7.109453] Bluetooth: HCI socket layer initialized [ 7.111373] Bluetooth: L2CAP socket layer initialized [ 7.113301] Bluetooth: SCO socket layer initialized [ 7.154252] Bluetooth: hci0: read Intel version: 3707100180012d0d00 [ 7.298260] Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-hw-37.7.10-fw-1.80.1.2d.d.bseq [ 7.346464] Bluetooth: hci0: Intel Bluetooth firmware patch completed and activated [ 8.475026] Bluetooth: RFCOMM TTY layer initialized [ 8.476920] Bluetooth: RFCOMM socket layer initialized [ 8.478797] Bluetooth: RFCOMM ver 1.11 [ 67.041180] Bluetooth: HIDP (Human Interface Emulation) ver 1.2 [ 67.041193] Bluetooth: HIDP socket layer initialized [ 67.042339] input: Bluetooth Laser Mouse as /devices/pci0000:00/0000:00:14.0/usb3/3-7/3-7:1.0/bluetooth/hci0/hci0:256/0005:04B4:0033.0001/input/input10 [ 67.042478] hid-generic 0005:04B4:0033.0001: input: BLUETOOTH HID v6.11 Mouse [Bluetooth Laser Mouse] on 80:19:34:5a:67:51 -- 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
