https://bugzilla.kernel.org/show_bug.cgi?id=214111 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@xxxxxxxxxxxxxxx Reporter: bryanhoop@xxxxxxxxx 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.
