Hello. I'm using BlueZ 5.55 and Linux 5.10.12. After following Gentoo guide to connect DS4 with bluetooth - https://wiki.gentoo.org/wiki/Sony_DualShock#DualShock_4 - I was able to successfully pair, trust and connect the gamepad. [bluetooth]# pair A4:53:85:AF:F5:05 Attempting to pair with A4:53:85:AF:F5:05 [CHG] Device A4:53:85:AF:F5:05 Connected: yes [CHG] Device A4:53:85:AF:F5:05 UUIDs: 00001124-0000-1000-8000-00805f9b34fb [CHG] Device A4:53:85:AF:F5:05 UUIDs: 00001200-0000-1000-8000-00805f9b34fb [CHG] Device A4:53:85:AF:F5:05 ServicesResolved: yes [CHG] Device A4:53:85:AF:F5:05 Paired: yes Pairing successful [CHG] Device A4:53:85:AF:F5:05 WakeAllowed: yes Authorize service [agent] Authorize service 00001124-0000-1000-8000-00805f9b34fb (yes/no): yes [Wireless Controller]# trust A4:53:85:AF:F5:05 [CHG] Device A4:53:85:AF:F5:05 Trusted: yes Changing A4:53:85:AF:F5:05 trust succeeded [Wireless Controller]# info Device A4:53:85:AF:F5:05 (public) Name: Wireless Controller Alias: Wireless Controller Class: 0x00002508 Icon: input-gaming Paired: yes Trusted: yes Blocked: no Connected: yes WakeAllowed: yes LegacyPairing: no UUID: Human Interface Device...

After some "debugging" I've noticed that for some reason plugging DS4 with usb cable prints those lines in bluetoothctl: [CHG] Device A4:53:85:AF:F5:05 Connected: no [CHG] Device A4:53:85:AF:F5:05 Trusted: no Authorize service [agent] Authorize service 00001124-0000-1000-8000-00805f9b34fb (yes/no): And after some time: [agent] Authorize service 00001124-0000-1000-8000-00805f9b34fb (yes/no): Request canceled [DEL] Device A4:53:85:AF:F5:05 Wireless Controller So my guess is while I'm doing my "buisness", authorization request gets cancelled and BlueZ automatically deletes the device. But why BlueZ requesting authorization in the first place if I'm plugging my gamepad through usb? Inetestingly, authorization is requested every time I plug my gamepad with USB, no matter if my device is already in "trusted" state. I'm not sure if this is bug with BlueZ, Linux kernel or if it's even a bug at all, but since BlueZ deletes my device, I decided to write this to linux-bluetooth mailing list. I am happy to provide further information if required. Thanks.
