Have you tried some troubleshooting? e.g:
Try unplugging one peripheral at a time. If the error disappears when unplugging one peripheral, suspect a fault there, or with its cable.
If that doesn't shed light on the problem, try connecting each device directly without the hub. If that works without an error warning, I'd suspect a faulty hub. Or perhaps, the hub needs to be powered to support multiple peripherals.
If a direct connection with each device gives you the same warning, I'd suspect a faulty port or cable. (Try different cable or port).
