    5i5RYK bluetooth stopped working completely

    jmw0

      A few days ago, the bluetooth on my 5i5RYK stopped working completely without any clear explanation. At first I thought it was a bad package or kernel update from Ubuntu. I tried earlier kernels, turned secure boot on and off, and none of it worked. I'm on the latest version of visual BIOS (0246). I tried booting from a live CD from a few weeks ago when it was working fine, and I'm seeing the same errors on the console that don't look good - something appears to have broken at a pretty low level. Is there anything I can try before contacting Intel about warranty service?

       

      This is what was normal:

        Apr 11 10:54:54 nuc kernel: [    1.596466] usb 1-7: new full-speed USB device number 5 using xhci_hcd

        Apr 11 10:54:54 nuc kernel: [    1.724700] usb 1-7: No LPM exit latency info found, disabling LPM.

        Apr 11 10:54:54 nuc kernel: [    1.725448] usb 1-7: New USB device found, idVendor=8087, idProduct=0a2a

        Apr 11 10:54:54 nuc kernel: [    1.795948] Bluetooth: hci0: Intel device is already patched. patch num: 09

      Now, when I boot up, I see this:

        Apr 19 13:59:12 nuc kernel: [   12.970997] usb 1-7: new full-speed USB device number 9 using xhci_hcd

        Apr 19 13:59:12 nuc kernel: [   13.082923] usb 1-7: device descriptor read/64, error -71

        Apr 19 13:59:12 nuc kernel: [   13.298759] usb 1-7: device descriptor read/64, error -71

      Or this in syslog:

        Apr 19 14:00:15 nuc kernel: [   77.818033] usb 1-7: USB disconnect, device number 14

        Apr 19 14:00:15 nuc kernel: [   77.818313] Bluetooth: hci0 sending initial HCI reset command failed (-19)

      From the linux errno definitions, -71 is "protocol error" and -19 is "no device" (probably since it disconnected just before). The system then keeps trying to load the driver again and again but it disconnects immediately.
