This specific hardware ID is most frequently associated with the following Acer Extensa series laptops: Acer Extensa 5220 Acer Extensa 5620 Acer Extensa 4620 Acer Extensa 7620 3. Driver Requirements & Compatibility

Because IrDA technology is largely obsolete, modern operating systems (Windows 10 and 11) often flag this as an "Unknown Device" in the Device Manager. Legacy Support: Officially supported on Windows XP Windows Vista Driver Version: The standard driver often cited is version 6.0.6001.18000 (dated 2006-06-21). Modern Workaround:

If the device appears as "Unknown" on Windows 8.1 or 10, users typically need to manually point the Device Manager to legacy Vista or Win7 driver packages provided by Acer or via repositories like DriverIdentifier 4. Implementation Status

If you are seeing this ID, it is likely because the BIOS/UEFI has the Infrared Port enabled

, but the OS lacks the functional driver. In most modern use cases, this device can be safely disabled in the BIOS

to clear the "Unknown Device" warning, as IrDA peripherals are no longer in common use. Do you need help locating a specific driver file or instructions on how to disable this hardware in your BIOS settings?

Finding an "Unknown Device" with the hardware ID ACPI\NSC6001 in your Windows Device Manager usually points to a missing driver for a legacy IrDA Fast Infrared Port. While infrared technology is less common today, this specific ACPI identifier is frequently seen on older laptops from manufacturers like Acer (specifically the Extensa and TravelMate series) and HP. What is ACPI\NSC6001?

The identifier ACPI\NSC6001 (or ACPI\VEN_NSC&DEV_6001) corresponds to an infrared communication chip manufactured by National Semiconductor.

ACPI: Advanced Configuration and Power Interface, which helps the operating system manage hardware power. NSC: The vendor code for National Semiconductor.

6001: The specific device ID for their Fast Infrared (FIR) controller.

In older mobile computing, this port allowed for wireless data transfer between laptops, PDAs, and early mobile phones before Bluetooth and Wi-Fi became the industry standards. Why is it showing as an "Unknown Device"?

If you have recently reinstalled Windows (especially Windows 7, 10, or 11) on an older laptop, the system may not automatically include the legacy drivers for this specific infrared hardware. Because the OS cannot identify the chip's function without a driver, it labels it as an Unknown Device with a yellow exclamation mark. How to Fix the ACPI\NSC6001 Driver Issue 1. Identification via Device Manager Before downloading anything, confirm the ID: Right-click the Start button and select Device Manager. Find the Unknown Device (usually under "Other devices"). Right-click it and choose Properties. Go to the Details tab.

Select Hardware Ids from the Property dropdown. You should see ACPI\NSC6001. 2. Download the Correct Driver

Since this is legacy hardware, the most reliable drivers are often hosted on manufacturer support pages or reputable driver repositories:

Acer Users: Check the Acer Support site for your specific model (e.g., Extensa 5220, 5620, or TravelMate 6593). Look for "Infrared" or "IrDA" drivers.

Third-Party Repositories: Sites like DriverIdentifier and DriverScape maintain archives of the 6.0.6001.18000 driver version, which is the standard for this chip. 3. Manual Installation Steps

If the driver comes as a .zip or folder without an installer:

In Device Manager, right-click the Unknown Device and select Update driver. Choose "Browse my computer for drivers". | Symptom | Likely Cause | Fix |

Select "Let me pick from a list of available drivers on my computer".

Click "Have Disk..." and browse to the folder where you extracted the downloaded driver files.

Select the .inf file and follow the prompts to finish the installation. Do You Actually Need This Driver?

For most modern users, the answer is no. Infrared ports are rarely used today. However, leaving an "Unknown Device" in your Device Manager can sometimes cause minor system instability or prevent the laptop from entering deep sleep modes properly. Installing the driver—even if you never use the infrared port—ensures a "clean" Device Manager and optimal power management.

Alternatively, if you don't use infrared, you can often Disable the device in Device Manager to stop Windows from alerting you about the missing driver. IrDA Fast Infrared Port Driver for Acer - Extensa 5620

The hardware ID ACPI\NSC6001 (often appearing as *NSC6001) refers specifically to a legacy IrDA Fast Infrared Port manufactured by National Semiconductor.

While it is frequently flagged as an "Unknown Device" in modern operating systems, it represents an older era of wireless data exchange that preceded the widespread adoption of Bluetooth and Wi-Fi. Hardware Identification and Origin

Manufacturer: The "NSC" prefix in the ID stands for National Semiconductor, a major American semiconductor company (now part of Texas Instruments).

Device Type: It is an IrDA (Infrared Data Association) compliant fast infrared port.

Primary Function: This device was designed for short-range wireless communication using infrared light beams, allowing laptops to sync with printers, PDAs, and mobile phones without physical cables.

Common Systems: It was a standard feature on many mid-to-late 2000s business and consumer laptops, particularly the Acer Extensa (5220, 5620, 7620) and TravelMate (5720) series. Technical Role in ACPI

The Advanced Configuration and Power Interface (ACPI) uses these unique IDs to tell the operating system how to manage the hardware's power states and resources.

Enumeration: When a system boots, the ACPI BIOS exposes the device tree to the OS. If the OS sees NSC6001, it searches its driver database for a matching "Fast Infrared Port" driver.

Legacy Support: Because infrared technology is largely obsolete in modern portable computing, newer versions of Windows (like Windows 10 and 11) often fail to automatically assign a driver, causing it to appear in Device Manager as a yellow-triangle "Unknown Device". Driver and Troubleshooting

If you see this ID in your Device Manager, it is almost certainly a remnant of an infrared port that you likely do not use.

Driver Version: The standard legacy driver for this device is version 6.0.6001.18000, released around 2006.

Necessity: For most modern users, this device can be safely disabled in the Device Manager if you do not plan to use infrared data transfers.

Installation: If you must use it, you can often find the driver on the support pages for older Acer laptops, such as the Acer Extensa 5620.

The specific string NSC6001 is a vendor-and-device identifier.

This is the native environment for this hardware. You need the specific chipset drivers.

If you are seeing this error on a modern version of Windows, it is highly likely that the hardware is too old to be fully supported, or you are running a modern OS on very old hardware (like an old Thin Client or Netbook).

After fixing, take these steps to avoid recurrence:
