From 337cf8a2df1edd95007ce3f6dfad2564c2820e58 Mon Sep 17 00:00:00 2001 From: Liang Haowen Date: Mon, 12 Oct 2026 23:42:40 +0800 Subject: [PATCH] HID: add ALWAYS_POLL quirk for YJX-CHIP EWEADN wireless receivers The 2.4 GHz receiver in EWEADN G5 wireless mice (YJX-CHIP A8A5:2255) presents its mouse data on a standard interrupt IN endpoint. usbhid only submits read URBs for an input device while a userspace consumer holds it open, so on boot or replug the mouse pointer stays dead until something opens the node. The same receiver ships with a number of other EWEADN models (A6, A7, E7, E9, E11, G2SE A, GS02 Pro, S7, S9SE, X23), so the quirk covers the whole family.
