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)
