I run this command:

uname -r; lsusb; lspci -nnk | grep -iA2 net; rfkill list all; hciconfig -a; dmesg | egrep -i 'blue|firm'

this is the output:

The machine is an ASUS laptop, using Xubuntu 18.04.1 LTS

I installed the drivers for the wifi (MT7630E) and somehow they work (sometimes I need to reinstall them) but I was never able to get the bluetooth running, can you please help me? Thanks

  • What happens if you sudo hciconfig hci0 up – Jeremy31 Dec 25 '18 at 11:05
  • Hi @Jeremy31, thanks, this is the output: Can't init device hci0: Invalid request code (56) – Nicola Dec 25 '18 at 13:16
  • I found this guide but I don't understand what it means by "cd to your preferred build dir". What directory is the guide talking about? – Nicola Dec 30 '18 at 16:25

I put a patch based on what you found on my github, to install do

sudo apt install dkms git build-essential
git clone https://github.com/jeremyb31/newbtfix-4.15.git
sudo dkms add ./newbtfix-4.15
sudo dkms install btusb/4.0

Check results for mokutil --sb-state if it says Secure Boot is enabled, then Secure Boot will need to be disabled when you reboot, if it says Secure Boot disabled, mokutil not installed, or system doesn't support EFI variables, just reboot

  • thanks! It works! – Nicola Dec 31 '18 at 15:14
