@Jeronimo17 Do you still have any problems?
It works, with kernel 5.8, I would like to continue with the old one ...

I copy rtl8761bu_fw to /lib/firmware/rtl_bt/ and rename it to rtl8761b_fw.bin

Code: Select all

Thank you all, hopefully a patch is made that adds it to kernel 5.4

I went through the same problem here. I Bought this one http://www.orico.cc/us/product/detail/7218.html and my OS is Ubuntu 20 and kernel 5.4.0-48-generic. I'm so happy I found you all talking about the same problem.

What I did to get it working here:

1 - I uninstalled everything I tried before:

Code: Select all

sudo apt remove bluetooth bluez bluez-cups bluez-tools btscanner gnome-bluetooth python-bluez pulseaudio-module-bluetooth blueman blueman-manager
2 - I installed MPOW drivers downloaded from: https://mpow.s3-us-west-1.amazonaws.com ... +Linux.tgz (credits to FadySGhatas). To install I ran:

Code: Select all

sudo make install INTERFACE=all
3 - Rebooted

4 - When I ran: dmesg | grep Blue I saw that my bluetooth have been recognized

Code: Select all

[    2.095392] usb 1-1.5: Product: Bluetooth Radio
[    2.745979] Bluetooth: Core ver 2.22
[    2.746000] Bluetooth: HCI device and connection manager initialized
[    2.746005] Bluetooth: HCI socket layer initialized
[    2.746007] Bluetooth: L2CAP socket layer initialized
[    2.746009] Bluetooth: SCO socket layer initialized
[    2.749727] rtk_btusb: Realtek Bluetooth USB driver ver 3.1.9321f79.20200610-155144
[    4.624426] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[    4.624428] Bluetooth: BNEP filters: protocol multicast
[    4.624431] Bluetooth: BNEP socket layer initialized
[   12.839489] Bluetooth: RFCOMM TTY layer initialized
[   12.839494] Bluetooth: RFCOMM socket layer initialized
[   12.839499] Bluetooth: RFCOMM ver 1.11
Before installing MPOW drivers it looked like this:

Code: Select all

[ 7655.176012] Bluetooth: hci0: rtl: examining hci_ver=0a hci_rev=000b lmp_ver=0a lmp_subver=8761
[ 7655.176051] Bluetooth: hci0: rtl: loading rtl_bt/rtl8761a_config.bin
[ 7655.178154] bluetooth hci0: Direct firmware load for rtl_bt/rtl8761a_config.bin failed with error -2
[ 7655.178161] Bluetooth: hci0: rtl: loading rtl_bt/rtl8761a_fw.bin
[ 7655.180308] Bluetooth: hci0: rom_version status=0 version=1
[ 7655.180329] Bluetooth: hci0: cfg_sz 0, total size 20204
[ 7657.312083] Bluetooth: hci0: command 0xfc20 tx timeout
[ 7665.376131] Bluetooth: hci0: download fw command failed (-110)
5 - I installed all these:

Code: Select all

sudo apt install bluetooth bluez bluez-cups bluez-tools btscanner gnome-bluetooth python-bluez pulseaudio-module-bluetooth blueman blueman-manager rfkill -y
6 - Run the following to make sure the bluetooth is not locked for some reason:

Code: Select all

sudo rfkill list
If it is, just run:

Code: Select all

sudo rfkill unblock bluetooth
7 - Finally make sure bluetooth service is running:

Code: Select all

sudo service bluetooth start
I had to reboot once again and restart bluetooth service after booting (sudo service bluetooth restart). It's working 100% now.

Thank you very much, I have done just that and it works with the current kernel

Thank you!

I had the same problem and it worked only after disabling Secure Boot. Is that safe? Is there any way to make this work without disabling secure boot?

I wondered about it some time ago when I switched from Windows to Linux and I remember to find some answers here https://askubuntu.com/questions/843656/ ... ecure-boot

Same here. But that's due to the 5.9 kernel breaking bluetooth for many people/devices. There've been a lot of reports on the kernel bug tracker as well as the Arch forums. I booted the LTS kernel the other day but then remembered it doesn't have the hardware info that was added to the 5.8 kernel lol so obviously this didn't work. Unfortunately not much else you can do at this point than rollback to a previous kernel or patiently wait for an update. Kind of sucks, but there's a 5.10 RC out now, so fingers crossed it's fixed in the next release.
