NEC PCI to USB Open Host Controller Driver

The NEC PCI to USB Open Host Controller driver helps Windows communicate with the NEC USB controller that manages connected USB devices. You may need it after reinstalling Windows, adding a PCI USB expansion card, or finding a missing-driver warning in Device Manager. Although listed under Printer, this device is a USB host controller rather than a printer; its driver supports the USB connection, while a connected printer may require its own software.

Key Features

• Enables Windows to recognize compatible NEC USB controller hardware and manage its USB ports.
• Provides controller-level support for compatible peripherals, including keyboards, mice, and USB printers.
• Can help resolve controller detection problems caused by a missing, damaged, or incompatible driver.
• Works with Windows USB services to handle device connections and data transfers, subject to the controller’s hardware capabilities.

Before choosing a NEC PCI to USB Open Host Controller driver download for Windows, check the package’s compatibility with your exact hardware and operating system. For Windows 11, 10, 8, or 7, confirm both the supported version and system architecture; a legacy driver is not automatically compatible with Windows 10/11. Select the latest version that explicitly supports your controller, rather than assuming the newest package is suitable. If choosing a free download, verify its source and digital signature before running it.

How to Install NEC PCI to USB Open Host Controller Driver

1. Open Device Manager and locate the NEC controller under Universal Serial Bus controllers or Other devices. Open Properties and check Details > Hardware Ids to identify the hardware.
2. Check your Windows version and system architecture in System settings. Look for a matching driver through Windows Update or the computer or expansion-card manufacturer’s support resources.
3. Download the compatible package and extract it if necessary. Save your work before you install the driver, as connected USB devices may temporarily stop responding.
4. Run the supplied installer, if available. Otherwise, right-click the controller in Device Manager, select Update driver > Browse my computer for drivers, and choose the extracted driver folder.
5. Restart if prompted, then check Device Manager for warnings and test a connected USB device. If problems begin after installation, use Roll Back Driver when available.

Keep the driver updated through trusted sources, especially when an update addresses a problem you are experiencing. If the controller works reliably and no compatible replacement is offered, avoid forcing an unsupported package onto your system.

Common Issues and Fixes

• Install fails or Code 10/28: Use the NEC OHCI driver package matching your Windows version, run setup as administrator, and allow unsigned legacy drivers only if required. If Windows rejects the INF, update via Device Manager > Browse my computer.
• Device not detected/Unknown PCI device: Reseat the NEC card, try another PCI slot, enable PCI USB in BIOS, and confirm the PCI vendor/device ID (NEC 1033) appears in Device Manager before installing the host-controller driver—not a USB hub driver.
• Version conflicts/Code 31 or crashes: Remove old or hidden NEC USB host-controller entries, roll back to the Microsoft OHCI driver if stable, and avoid mixing OEM USB stacks; reboot after each change.
