USB host-side correlation
Establish the direct USB connection first.
Seven-port powered USB hub adds ports and a shared USB path. Compare a direct host connection with the powered hub before attributing a disconnect to the board or storage device.
- Check the supplied power adapter, upstream cable and the device’s power needs. Establish a known-good direct connection with the device’s supported software.
- Repeat the same operation through the hub, changing one attached device at a time and recording which port and cable are in use.
- Keep operating-system USB logs separately. If the PCIe host controller is also implicated, inspect that controller’s own metadata in the Header7F workbench.
Header7F does not enumerate the hub, switch its ports, measure USB bandwidth or read its power draw. The host controller’s PCIe evidence is a separate view.
