My broadcom bluetooth device was not working so I followed the solution posted on the following link: Bluetooth Broadcom 43142 isn't working

I downloaded the latest driver from broadcom, found the file i needed, converted it to hcd and used the name BCM.hcd after checking my dmesg log. Now my bluetooth device is not even starting. I am getting the following messages on my dmesg log:

[   22.040870] Bluetooth: hci0: BCM: Reading local version info failed (-110)

[   24.049006] Bluetooth: hci0 command 0x1001 tx timeout

lsusb still recognises my bluetooth device 

Bus 001 Device 007: ID 0a5c:21d7 Broadcom Corp. BCM43142 Bluetooth 4.0

Also, I removed the file I had pasted into /lib/firmware/brcm earlier. Now, the dmesg log shows the following messages:

[   23.867936] Bluetooth: hci0 command 0x1001 tx timeout

[   31.863859] Bluetooth: hci0: BCM: Reading local version info failed (-110)

[   32.062376] Bluetooth: BNEP (Ethernet Emulation) ver 1.3

[   32.062378] Bluetooth: BNEP filters: protocol multicast

[   32.062382] Bluetooth: BNEP socket layer initialized

  • This looks like some bug. What is the kernel version? – Pilot6 Sep 01 '16 at 15:35
  • Is kernel version the OS version? If so then it is 16.04 – yolo7398 Sep 01 '16 at 15:38
  • Kernel version is not the OS version, but in 16.04 it should be 4.4. You can see it by uname -r. Are you sure you converted the correct file to hcd? – Pilot6 Sep 01 '16 at 15:40
  • I converted a file for this adapter. https://www.dropbox.com/s/bsowlvv3f9my7kj/BCM43142A0-0a5c-21d7.hcd?dl=0 For kernel 4.4 you need to rename it to BCM.hcd. – Pilot6 Sep 01 '16 at 15:41
  • I named it BCM.hcd before copying it. Also, I would suggest an edit to your previous answer. In the new version of the driver, the .inf file is not named bcbtums-win8x86-brcm.inf. Instead, it is named bcbtums.inf – yolo7398 Sep 01 '16 at 15:44
  • It does not really matter how the inf file is called. – Pilot6 Sep 01 '16 at 15:45
  • Also, I tried both the driver you posted and also the latest one from broadcomm. Both show the same results – yolo7398 Sep 01 '16 at 15:45
  • Try the file I posted now. If it still does not work, report a bug. – Pilot6 Sep 01 '16 at 15:46
  • It does not work. I will report the bug. Thanks for your help – yolo7398 Sep 01 '16 at 15:52
