https://bugzilla.kernel.org/show_bug.cgi?id=211013 Bug ID: 211013 Summary: Cannot find ath3k bluetooth controller attached on USB Product: Drivers Version: 2.5 Kernel Version: 5.10.x Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: cth451@xxxxxxxxx Regression: No bluetoothctl (from bluez 5.55) cannot find the bluetooth controller on my ar5b22 wireless adapter. However /sys/class/bluetooth/hci0 points to the correct device. rfkill would toggle blocking/unblocking state without problem, but bluez won't be able to find the controller regardless. Steps to reproduce: 1. Boot up the system 2. Run 'bluetoothctl list'. This will print nothing on my system since this ath3012 is the only bluetooth adapter present, but wasn't found. 3. I checked /sys/class/bluetooth/hci0, where the device file pointed to the correct USB device number.
