From d49f8d9680ee3f7f4e0339467cf0a244158c1adb Mon Sep 17 00:00:00 2001 From: Roman Bolotov Date: Wed, 23 Sep 2026 09:45:27 +0300 Subject: [PATCH] ALSA: usb-audio: Add quirk flag for ASUS SupremeFX Hi-Fi The ASUS SupremeFX Hi-Fi (0b05:1826, 0b05:1827) does not survive USB autosuspend. After a suspend/resume cycle the firmware degrades: HID probes begin to fail and the descriptors it returns become corrupted, until the device stops responding entirely and needs a physical power cycle to recover. Add QUIRK_FLAG_DISABLE_AUTOSUSPEND for both product IDs. Verified on 7.2.6 through the quirk_flags module parameter, with no code change, and with the local udev rules that had been forcing power/control commented out, so the parameter was the only mechanism in play. Both IDs were passed as 0b05:1827:disable_autosuspend;0b05:1826:disable_autosuspend The device then stayed awake across 2.5 hours (runtime_suspended_time remained 0), survived a system suspend/resume cycle, and continued to work afterwards with no failed probes and no power cycle needed.
