From 17eb20505c550161b4bd704fc24b2b9cb1b5ef0b Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Mon, 9 Feb 2026 13:28:04 -0800 Subject: [PATCH] Fix the 8BitDo Ultimate 2D Wireless Controller showing up multiple times This controller has 3 interfaces, one for the Xbox gamepad protocol, and two HID interfaces. We should only handle the Xbox interface in the Xbox driver.
