Describe the Bug

The controller can be paired properly (it rumbles and X logo stays lit, input works in steam and when testing with evtest), but after turning it off and on again it doesn't connect anymore. I have to remove the device from paired devices and pair it again. It reconnects properly on Winndows on the same PC (with the same bluetooth controller).

Steps to Reproduce

1. Pair your controller
2. Turn off the controller
3. Turn it back on
4. Controller doesn't reconnect to the PC. Trying to manually connect it using bluetoothctl or KDE bluetooth applet doesn't work either.

Expected Behavior

Controller should automatically connect back to the PC when turned on. At least it should allow to connect manually without pairing it again.

Additional Context

I've tried various tweaks mentioned in different threads, like:

• Enabling FastConnectable
• Setting JustWorksRepairing to always
• Setting Privacy to device
• Disabling ERTM
• Copying pairing keys from Windows

In all possible combinations. At first I wasn't able to pair my controller at all, but it started working after pairing it at least once on Windows (through bluetooth. Pairing via dongle or connecting through the USB cable didn't work, there was no firmware updates either).

I've resolved the issue recently by completely removing IdentityResolvingKey section (together with data inside this section) from /var/lib/bluetooth/adapter_mac/device_mac/info file. This issue and workaround for it is described on Arch wiki.
