JIRA: https://issues.redhat.com/browse/RHEL-170872 Upstream Status: since v7.0 commit b3b1c68fb726907ea35ac172906705fe62c7fdaf Author: Nguyen Dinh Dang Duong <dangduong31205@gmail.com> Date: Sat Jun 28 00:04:23 2025 +0700 HID: rapoo: Add support for side buttons on RAPOO 0x2015 mouse This patch adds support for handling the side buttons on the RAPOO 0x2015 wireless mouse. These buttons were previously not generating input events due to missing driver logic. The new code handles raw HID input report with Report ID 1 and maps the side buttons to KEY_BACK and KEY_FORWARD using the input subsystem. Tested on a RAPOO mouse with USB ID 24AE:2015.
