How to Install NEC PCI to USB Enhanced Host Controller (B0) Driver

1. Open Device Manager and locate the controller, usually under Universal Serial Bus controllers or Other devices. Check its Properties, including Hardware IDs, to confirm the device matches.
2. Check Windows Update for a suitable driver first. If using a separate free download, verify that its source is trustworthy and that it supports your Windows version and architecture.
3. Save your work before you install the driver. Updating a USB controller can temporarily disconnect attached devices, so avoid doing this during transfers to USB storage.
4. Run the package’s installer, if included. For an extracted driver package, right-click the controller in Device Manager, select Update driver, and browse to the folder containing the driver files. Menu wording varies by Windows version.
5. Restart if prompted, then check Device Manager for warnings and test your connected USB devices.

Keep the driver updated through Windows Update or a verified, compatible package when an update addresses a relevant issue. The latest version is only useful if it matches your system; a higher version number alone does not guarantee better performance or compatibility.
