From 2353af214b104e8680ec2e8ed1f7e0b72dc6cc6b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Filipe=20La=C3=ADns?= Date: Mon, 9 Sep 2019 15:57:59 +0100 Subject: [PATCH] hidpp20: fallback to 1st profile when no 8100 profile is active MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the windows driver puts a device in host mode it will mark all 8100 profiles as disabled. If no 8100 profile is enabled no libratbag profile will get enabled. This patch prevents this by marking the first profile as enabled if no profile is already enabled.
