From 48144e83daba5619adaf0baf4fcea98082dce818 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Exp=C3=B3sito?= Date: Fri, 24 May 2024 13:21:35 +0200 Subject: [PATCH] HID: uclogic: Support HUION devices with up to 20 buttons MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The HID descriptor for HUION tablets was limited to 13 buttons. However, there are devices with more buttons in their frames. So far, the device with more buttons released by HUION is the Huion Kamvas Pro 24 (GT-240, QHD) [1], with 20 buttons. Tweak the HID descriptor to support it.
