When you troubleshoot issues with a FireWire controller card, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue: FireWire cables FireWire devices FireWire controller card To test your setup components, try the following: Use the FireWire cables, devices, and controller card in another setup to see if the problem is with the components or the setup. Use a different FireWire cable, device, and controller card in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup. When you test the FireWire device and controller card, it is recommended that you do the following: Press the Windows key + R , type devmgmt.msc , and press Enter to open Device Manager . Check to see if your devices are listed under IEEE 1394 controllers . If you do not see the FireWire controller card listed in Device Manager, refer to the following FAQ: https://www.startech.com/en-us/faq/pci-pcie-cannot-boot-os-or-detect-windows .

What DC barrel connector power plug types do StarTech.com products use, and what are their dimensions?
StarTech.com DC barrel connector plug types are defined in the “Plug Type” field of the technical specifications, using a letter code that specifies the connector’s outer diameter (OD) and inner diameter (ID) in millimeters for power adapter compatibility. Explanation: In StarTech.com technical specifications, the “Plug Type” field is a standardized identifier for the exact DC barrel connector size required to power a product. Each plug type is assigned a letter code that corresponds to a specific combination of outer diameter (OD) and inner diameter (ID), measured in millimeters. Common DC barrel plug type dimensions Plug Type OD ID A 2.35 mm 0.7 mm B 4.0 mm 1.7 mm C 4.75 mm 1.7 mm H 3.4 mm 1.3 mm L 5.0 mm 2.5 mm M 5.5 mm 2.1 mm N 5.5 mm 2.5 mm The DC barrel connector plug type must match both the outer diameter and inner diameter exactly. A mismatch between the StarTech.com product requirement and the power adapter connector can prevent proper fit or stable power delivery, which may result in device startup failure or intermittent operation. The plug type defines only the physical connector size. The plug type does not define electrical power requirements such as voltage, current, or polarity. The power adapter used with a StarTech.com product must match the product’s specified electrical requirements. Using an incompatible power adapter can cause device malfunction or permanent damage. This standardized DC barrel connector plug type system enables IT professionals and procurement teams to verify connector dimensions, ensure power adapter compatibility, standardize hardware deployments, and identify the correct replacement power supply for StarTech.com products.
