Root cause: /sys/bus/pci/devices/0000:00:0d.0/power/control was auto. Fix: Removed xhci_hcd from TLP's RUNTIME_PM_DRIVER_DENYLIST so TLP sets xHC= I to on on AC. Result: Hot-plug works. Dock enumerates on USB 3.0 with ethernet at 5000M. Note: TLP ships with xhci_hcd in the default denylist (defaults.conf), leav= ing xHCI at kernel default (auto). --=20 You may reply to this email to add a comment.
