Broadcom bluetooth adapter is not recongnized (0a5c:2045)

Question

I cannot find the corresponding windows hex file too for 0a5c:2045 to try this solution : https://github.com/advancingu/XPS13Linux/issues/1

As requested the log of lspci -knn | grep Net -A2; lsusb:

The adapter I am using has id 0a5c:2045 , for which i could not get the windows hex file too.

  $ uname -a; hciconfig -a

I had tried the solution mentioned above but the hex file for 0a5c:2045 is not available in the cab file :( — Ankur Anandapu, Nov 28 '15 at 17:42
Edit to include uname -a; hciconfig -a as there might be a fix — Jeremy31, Nov 29 '15 at 14:15
Included the uname destails , but no output from hciconfig -a , please check — Ankur Anandapu, Nov 30 '15 at 16:22

There is an issue with the BCM2045 that was recently fixed upstream, I have applied a patch to the kernel source

sudo apt-get install build-essential linux-headers-$(uname -r)
wget https://www.dropbox.com/s/y4c8nm8fr1f2amx/bluetooth-4.2.tar.gz
tar -zxvf bluetooth-4.2.tar.gz
cd bluetooth
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo mv /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko /lib/modules/(uname -r)/kernel/drivers/bluetooth/btusb.ko.bak
sudo cp btusb.ko /lib/modules/4.2.0-18-generic/kernel/drivers/bluetooth/btusb.ko

Reboot and see if it corrects the issue with the bluetooth, if it is confirmed to work, I can make a DKMS version that will not have to be recompiled when you update to a newer kernel

The patch I used originated from here

Sorry, but i could not see bluetooth device on hcitool scan after the above. – Ankur Anandapu Dec 02 '15 at 06:17
Anything from hciconfig -a – Jeremy31 Dec 02 '15 at 10:23
no output from 'hciconfig -a' – Ankur Anandapu Dec 08 '15 at 04:24
You may just have to wait for Ubuntu to patch their own kernel using the upstream patch – Jeremy31 Dec 08 '15 at 11:18
