From 191edc5e2e515aab1075a3f0ef23599e80be5f59 Mon Sep 17 00:00:00 2001 From: Kai-Heng Feng Date: Thu, 8 Mar 2018 17:17:17 +0200 Subject: xhci: Fix front USB ports on ASUS PRIME B350M-A When a USB device gets plugged on ASUS PRIME B350M-A's front ports, the xHC stops working: [ 549.114587] xhci_hcd 0000:02:00.0: WARN: xHC CMD_RUN timeout [ 549.114608] suspend_common(): xhci_pci_suspend+0x0/0xc0 returns -110 [ 549.114638] xhci_hcd 0000:02:00.0: can't suspend (hcd_pci_runtime_suspend returned -110) Delay before running xHC command CMD_RUN can workaround the issue. Use a new quirk to make the delay only targets to the affected xHC.
