Direct PCIe evidence
Start at the card’s host connection.
StarTech Dual-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.
- Identify the card’s PCI address and supported driver on Linux. Collect its metadata with the Header7F collector and review the output.
- Import the JSON into the workbench. Check visibility, driver binding, resources and the available PCIe link context.
- 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.
