Dualshock 4 usb issues

["shhhum" <shum@posteo.net>]

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

However, recently I've started to notice that after plugging my DS4 with usb I
can no longer connect my DS4 with bluetooth. 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.
