Posted May 10, 20223 yr I bought a bluetooth usb device using rtl8761bu chip, it can drive in unraid6.9.2 version, but when I run `bluetoothctl` scan on, it can't scan any device. When looking for information, I found the kernel patch and the temporary solution. patch: https://patchwork.kernel.org/project/bluetooth/patch/[email protected]/ temp: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1955916/comments/21 I followed the temporary solution and completed the following repair script #!/bin/sh set -e ko_path=/lib/modules/"$(uname -r)"/kernel/drivers/bluetooth sudo cp "${ko_path}"/btusb.ko.xz "${ko_path}"/btusb.ko.xz.bak xz -dkf "${ko_path}"/btusb.ko.xz xxd "${ko_path}"/btusb.ko | sed 's/ca04 0540/5025 6187/g' |xxd -r > "${ko_path}"/btusb.ko.mod mv "${ko_path}"/btusb.ko.mod "${ko_path}"/btusb.ko xz -f "${ko_path}"/btusb.ko chmod 644 /lib/modules/"$(uname -r)"/kernel/drivers/bluetooth/btusb.ko.xz sudo cp /boot/config/custom/firmware/rtl8761b* /lib/firmware/rtl_bt chmod 644 /lib/firmware/rtl_bt/rtl8761b* modprobe -r btusb && modprobe btusb the usb device worked successfully. Please let me know if this is fixed in 6.10. Edited May 10, 20223 yr by VergilGao
May 21, 20223 yr Author Glad to see that this problem has been fixed in 6.10.0, but because unraid lacks the necessary driver, users using rtl8761bu need to release the driver to the corresponding location by themselves Note that the corresponding files are named as described in this post https://linuxreviews.org/Realtek_RTL8761B#comment-2320
August 6, 20222 yr Also +1'ing this. Home assistant now supports Bluetooth. Those of us running Home Assistant via docker will hit this issue. I'm not sure how to get the above work arounds working so as for now, I can't use the USB bluetooth receiver I bought to control bluetooth devices with Home Assistant.
August 6, 20222 yr I was able to get it working by following this thread I installed "nerd tools" via community apps, went to the plugins tab in unraid and clicked the "nerd tools" icon... and then i searched for "bluez" and turned it on. Next I putting the following in my /boot/config/go file. I also ran all it manually once # Configure the Bluetooth driver sudo curl -L https://raw.githubusercontent.com/Realtek-OpenSource/android_hardware_realtek/rtk1395/bt/rtkbt/Firmware/BT/rtl8761b_config -o /tmp/rtl8761bu_config.bin sudo mv /tmp/rtl8761bu_config.bin /lib/firmware/rtl_bt/rtl8761bu_config.bin sudo curl -L https://raw.githubusercontent.com/Realtek-OpenSource/android_hardware_realtek/rtk1395/bt/rtkbt/Firmware/BT/rtl8761b_fw -o /tmp/rtl8761bu_fw.bin sudo mv /tmp/rtl8761bu_fw.bin /lib/firmware/rtl_bt/rtl8761bu_fw.bin # Start Bluetooth /etc/rc.d/rc.bluetooth start Then I had to unplug the usb device, plug it back in and running some combination of the following made it work /etc/rc.d/rc.bluetooth stop /etc/rc.d/rc.bluetooth start sudo bluetoothctl
August 11, 20222 yr I tried this and can't get it to work. In home assistant, it has an error on the integrations page for the bluetooth integration: Retrying setup: Failed to start Bluetooth: adapter 'hci0' not found What exactly do you have passed in to the container? I have the path /var/run/dbus pointed to /var/run/dbus AND I have the device /dev/bus/usb/003/013 (as that's what's showing up for the bluetooth adapter in Tools > System Devices).

Adding these lines to the end of your go script right after moving the files into /lib/firmware/rtlbt and before running `/etc/rc.d/rc.bluetooth start` should mean you don't have to mess around unplugging/replugging the adapter after a reboot.
