Direct PCIe evidence

Start at the card’s host connection.

StarTech Four-port RS-232 16950 adapter exposes a PCIe controller. Use saved host evidence to check whether the card appears correctly before debugging the device attached to its ports.

  1. Identify the card’s PCI address and supported driver on Linux. Collect its metadata with the Header7F collector and review the output.
  2. Import the JSON into the workbench. Check visibility, driver binding, resources and the available PCIe link context.
  3. Keep a baseline capture and add relevant reported faults. Test downstream serial, parallel or FireWire behavior using the appropriate supported software.

Header7F does not decode UART, RS-232/485, parallel-port or FireWire traffic. PCIe evidence alone does not validate the attached device or its application protocol.
