From e31942147bf5c7fe532f4703e6229c3ffd075dfe Mon Sep 17 00:00:00 2001 From: Jose Alberto Reguero Date: Thu, 19 Sep 2024 20:42:02 +0200 Subject: [PATCH] usb: xhci: Fix problem with xhci resume from suspend commit d44238d8254a36249d576c96473269dbe500f5e4 upstream. I have a ASUS PN51 S mini pc that has two xhci devices. One from AMD, and other from ASMEDIA. The one from ASMEDIA have problems when resume from suspend, and keep broken until unplug the power cord. I use this kernel parameter: xhci-hcd.quirks=128 and then it works ok. I make a path to reset only the ASMEDIA xhci.
