            Bug ID: 214111
           Summary: rtl8761b usb bluetooth doesn't work following reboot
                    until unplug/replug
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.13.10
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Bluetooth
          Assignee: linux-bluetooth@vger.kernel.org
          Reporter: bryanhoop@gmail.com
        Regression: No

I'm not sure if this is the correct place to report this problem, but since the
firmware is so new I figure that it is probably a firmware bug.

I have a USB Bluetooth 5.0 dongle using the rtl8761b chipset that was recently
added to the kernel. It works fine until I reboot my computer, after which I am
unable to activate Bluetooth (from GNOME settings) until I unplug and replug
the dongle. Then everything starts working normally.

Logs:

After reboot (dongle not working):
