Pass-Through for User (COM13) Driver

The Pass-Through for User (COM13) driver helps Windows recognize and communicate with the USB-connected interface identified by this name on Hitachi hardware. It is intended for users who need to restore a missing COM port, resolve a driver-related detection problem, or set up compatible software that communicates through the device.

Key Features

• USB interface recognition: Provides the driver support Windows needs to identify the associated Hitachi interface rather than leave it listed as an unknown device.
• COM-port communication: Enables compatible applications to access the device through its assigned serial port. Although the device name includes COM13, Windows may assign a different port number after installation.
• Support for listed Windows releases: Supported operating systems include Windows 10, 8.1, 7, Vista, and XP; select a package that matches your specific release and system architecture.
• Driver maintenance: Installing the correct package can help address problems caused by a missing, damaged, or incompatible driver, though it will not resolve every connection issue.

How to Install Pass-Through for User (COM13) Driver

1. Confirm the device identity. Open Device Manager and locate the Hitachi interface under Ports (COM & LPT), USB devices, or Other devices. Check its hardware IDs in Properties to help verify the correct package.
2. Check Windows compatibility. Before choosing a Pass-Through for User (COM13) driver download for Windows, confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.
3. Download a matching package. Choose a trusted source and check whether its latest version supports your hardware and Windows release. If using a free download, verify its origin and avoid unrelated bundled software.
4. Install the driver. Extract the files if necessary, then run the supplied installer. Alternatively, select Update driver in Device Manager and browse to the extracted driver folder.
5. Verify the connection. Restart if prompted, reconnect the device, and check for warning icons in Device Manager. Configure your application to use the COM-port number Windows actually assigned.

Keep the driver updated when a verified, compatible update addresses a problem or adds needed support. Before replacing a working driver, retain a copy of the existing package so you can restore it if the new installation causes issues.
