https://bugzilla.kernel.org/show_bug.cgi?id=206457 Bug ID: 206457 Summary: Gamepad Dualshock4 CUH-ZCT2U doesn't pair or connect Product: Drivers Version: 2.5 Kernel Version: 5.5+ Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: arael78@xxxxxxxxx Regression: No Pairing the Dualshock4 controller does not complete correctly, even after several attempts. Once the pairing is apparently completed (I have to switch off the controller to interrupt the pairing process), when I try to connect it it doesn't stay connected. I have checked the dmesg and apparently there is a buffer overflow. I can pair a bluetooth headset to my laptop and the Dualshock4 pairs with my samsung tablet without problems but when I try to pair the dualshock4 to the laptop, running kernel 5.5 and current 5.5+ it doesn't work. I tried other kernels from 5.0 up. None worked.
