USB COM Port (COM43) Driver

The USB COM Port (COM43) driver helps Windows recognize the Clockworkmod-associated USB serial interface and lets compatible software communicate through its assigned COM port. You may need it when setting up the device for the first time, restoring a missing port, or troubleshooting a connection that appears with a warning in Device Manager.

Key Features

• USB serial communication: Provides the driver interface that compatible applications need to access the connected device as a COM port.
• Device recognition: Helps Windows identify the USB COM interface rather than leave it listed as an unknown device, provided the package matches its hardware ID.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual package for the correct Windows edition and 32-bit or 64-bit architecture.
• COM port configuration: Allows compatible software to use the port assigned by Windows. COM43 is a port designation, not a unique hardware model, and the number may differ between computers.

How to Install USB COM Port (COM43) Driver

1. Verify the device. Connect it, open Device Manager, and find the interface under “Ports (COM & LPT)” or “Other devices.” Open Properties → Details → Hardware Ids to help confirm the correct driver.
2. Check compatibility. Before choosing a USB COM Port (COM43) driver download for Windows, compare the package details with your operating system, architecture, and hardware ID. For Windows 10/11 systems, note that Windows 11 is not included in the listed support.
3. Download the matching package. Choose the latest version explicitly compatible with your setup. If a free download is offered, verify its source and avoid unrelated download managers or bundled utilities.
4. Install the driver. Extract the files if necessary, then run the included installer. Alternatively, use Device Manager’s “Update driver” option and browse to the extracted driver folder.
5. Confirm the connection. Restart if prompted, then check that the device appears without a warning icon. Select COM43—or whichever port Windows assigns—in the application that needs the connection.

Keep the driver updated when a compatible release addresses connection problems or supports a system change. Before an update, retain the working package or create a restore point so you can recover if needed; a newer driver is not automatically a better match for older Windows versions.
