From 05e6329443734a2a0aefb845d74375081d6626b6 Mon Sep 17 00:00:00 2001 From: Vicki Pfau Date: Fri, 7 Jul 2023 10:34:41 -0700 Subject: Input: xpad - fix support for some third-party controllers Some third-party controllers, such as the HORPIAD FPS for Nintendo Switch and Gamesir-G3w, require a specific packet that the first-party XInput driver sends before it will start sending reports. It's not currently known what this packet does, but since the first-party driver always sends it's unlikely that this could cause issues with existing controllers.
