My laptop, an MSI GS70 Stealth Pro, has build a build in Bluetooth device that Ubuntu seems to not recognize.

When I go to System Settings > Bluetooth it says No Bluetooth adapters found.

From what I've seen in other threads, I leave here some hopefully helpful info:

rfkill list:

How do I fix this problem?

    This is a QCA Rome chipset and it has the same bluetooth ID as an older bluetooth that is supported by the kernel. Qualcomm needs to find a way to fix this. This is the result from upstream about the device – Jeremy31 Jun 26 '16 at 11:59
  • I am building a DKMS package for this issue. – Pilot6 Jun 26 '16 at 12:05

This problem exists because Atheros re-used the chip VID and PID.

See this bug report

As a workaround you can patch the btusb.c module and change it from ath3k to Rome.

I've built a DKMS package to fix this issue and uploaded it to my PPA.


Install this deb and reboot. This should fix the issue.

    It fixed it right up! I've been without Bluetooth for such a long time. Thank you. – Ricardo Rodrigues Jun 26 '16 at 16:18
  • Update: for some reason, now the bluetooth works but it does not detect any devices. Last system update at 4th July. Should I hope another question? – Ricardo Rodrigues Jul 4 '16 at 20:56
  • Please post output of dkms status. – Pilot6 Jul 4 '16 at 20:58

    It looks OK. The problem is not related to kernel. It must be something user space. – Pilot6 Jul 4 '16 at 21:01

Ubuntu 16.04, Kernel version 4.4.0-116

My Device is

>> lspci -knn | grep bt -A2; lsusb
Bus 003 Device 008: ID 04ca:3011 Lite-On Technology Corp. 

>> lspci | grep -i ath
07:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 20)

I had to do the following (adding the Chipset-ID to btusb-driver-patch from Pilot6) to run my Bluetooth Adapter on Acer Aspire V17 Nitro VN7-791G-72FC with Atheros Combo-Card with Bluetooth Chipset Lite-On:

wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/bluetooth/+files/btusb-lp1542743-dkms_0.1_all.deb
mkdir tmp
dpkg-deb -R btusb-lp1542743-dkms_0.1_all.deb tmp
sudo nano tmp/usr/src/btusb-lp1542743-0.1/btusb.c 


"static const struct usb_device_id blacklist_table[] = {"

adding new line with the following code:

{ USB_DEVICE(0x04ca, 0x3011), .driver_info = BTUSB_QCA_ROME },

after compile, install and reboot:

sudo dpkg-deb -b tmp btusb-lp1542743-dkms_0.1_all_modifiedAdd3011.deb
sudo dpkg -i ./btusb-lp1542743-dkms_0.1_all_modifiedAdd3011.deb
sudo reboot

now all works fine. :-) I'm happy.

  • Pls explain exactly whats happening here: { USB_DEVICE(0x04ca, 0x3011), .driver_info = BTUSB_QCA_ROME }, \n Are you simply prepending 0x to the ID values of the bluetooth device? – Dawoodjee Jun 1 '19 at 20:36
