1) Power: Try a self‑powered hub/dock; avoid underpowered ports. 2) Cable: Swap to a short, known‑good, e‑marked C cable. 3) Port: Test other host ports; front‑panel headers can be noisy. 4) Lanes: High‑speed SSD + webcam on same hub? Separate them. 5) Drivers/FW: Update chipset, GPU, DisplayLink (if used), dock FW. 6) OS Power Saving: Disable selective suspend/USB power savings for critical devices. 7) Heat: NVMe enclosures throttle—add airflow or move devices. 8) Interference: 2.4 GHz dongles near USB 3.x cables can drop; use USB 2.0 extender.
