From 824deff87f5b1a2f32b9c3164191b0f5b22276b8 Mon Sep 17 00:00:00 2001 From: Rostislav Pehlivanov Date: Tue, 28 Jul 2015 08:38:47 +0100 Subject: [PATCH] HID: sony: Fix DS4 controller reporting rate issues This commit removes the cap on the DualShock 4 controller reporting rate when connected using Bluetooth. The previous value of '0xB0' capped the rate to only 20.83 Hz which many userspace utilities mistook as a sign of a bad signal. Since a 'B' and an '8' can look similar it's possible that someone mistook the one for another. The new value of '0x80' enables the full 1000 Hz peak reporting rate that the controller is capable of. Frank adds: "Back when the original code was written the purpose of that value was unknown and 0xB0 seemed to work so that's what ended up being used. Now that we know what it actually does and that 0x80 is a better choice I support this patch."
