Before Wi-Fi and Bluetooth achieved ubiquity, Fast Infrared (IrDA) ports allowed laptops to wirelessly sync data with early smartphones, PDAs, and printers over short, line-of-sight distances. Common Symptoms and Errors
Unlike standard serial IR (SIR) which is limited to 115.2 kbps, Fast Infrared (FIR) allows for data transfer rates up to Secure, Point-to-Point Connectivity:
The NSC6001 is a family of ACPI-compliant embedded controllers (EC) produced by National Semiconductor (now part of Texas Instruments) historically used in laptops and embedded systems to handle power management, thermal control, keyboard scanning, and other low-level platform functions. It implements standard ACPI EC interfaces so the operating system can interact with platform hardware through ACPI methods ( SB .EC and related objects).
| Cause | Explanation | |-------|-------------| | | Your motherboard's BIOS contains ACPI tables referencing an NSC6001 device, but Windows 10/11 no longer ships with a dedicated driver. | | Incorrect driver migration | Upgrading from Windows XP/Vista/7 to 10/11 carries over an entry for NSC6001 that no longer exists in the new OS. | | Chipset driver residue | Old Intel or VIA chipset drivers sometimes leave behind NSC references even after uninstallation. | | Virtual machine passthrough | Hyper-V or VMware passthrough of legacy PCI devices can erroneously create this ACPI entry. | acpi nsc6001
: The properties panel states that "The drivers for this device are not installed (Code 28)" .
If you need to install the driver manually via the .inf script file, verify your target platform parameters against the original release metrics: Specification Details ACPI\NSC6001 or ACPI\VEN_NSC&DEV_6001 Device Class Infrared Data Association (IrDA) Devices Primary Chip Vendor National Semiconductor Standard Driver Version 6.0.6001.18000 Original File Size ~35 KB to 38 KB Supported Deployments Windows XP, Vista, Windows 7, Windows 8, Windows 10
Legacy drivers meant for Windows 7 or 8 are frequently dropped from the native driver library of Windows 10 and Windows 11. Before Wi-Fi and Bluetooth achieved ubiquity, Fast Infrared
If you are still seeing this issue, are you using an older laptop model like an Acer TravelMate or Extensa, and did this appear after a Windows update? To help me guide you to the right solution, let me know: What are you using? What version of Windows (10 or 11) is installed? Microsoft Update Catalog
: Many older laptops allow you to "Disable Infrared" in the BIOS settings. This is the cleanest way to make the NSC6001 disappear.
