Altium JTAG over USB (COM30) Driver

The Altium JTAG over USB (COM30) driver enables Windows to recognize the USB-connected Altium JTAG interface and make it available to compatible development tools. It is intended for users who need to connect supported Altium hardware for programming, debugging, or other JTAG-related tasks. The COM30 label identifies the port assigned by Windows; the actual port number may differ on another computer.

Key Features

• Device recognition: Helps Windows identify the Altium USB interface rather than leave it listed as an unknown device.
• Development-tool connectivity: Provides the driver-level connection needed by compatible Altium software to communicate with supported hardware.
• COM port identification: Makes it easier to locate the assigned interface in Device Manager and select it in software that requires a port setting.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility of the individual driver package.

How to Install Altium JTAG over USB (COM30) Driver

1. Check your Windows version and architecture. Confirm whether your system uses 32-bit or 64-bit Windows. For Windows 10/11 users, note that Windows 10 is listed as supported, while Windows 11 compatibility is not confirmed here.
2. Select a compatible package. Before starting an Altium JTAG over USB (COM30) driver download for Windows, review the package details and choose the latest version that explicitly supports your hardware and operating system. If offered as a free download, verify its source and digital signature where available.
3. Prepare the installation files. Extract the archive if necessary and read any included instructions. Connect or disconnect the hardware as directed by the package documentation.
4. Install the driver. Run the supplied installer, if available. Otherwise, open Device Manager, locate the Altium interface or unidentified USB device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Reconnect the device or restart Windows if prompted. Check that Device Manager shows no warning icon, then open your compatible Altium software and select the assigned port if required.

Keep the driver updated when Altium provides a compatible release that addresses connection issues or supports your software setup. Before an update, retain a copy of the working package so you can restore it if needed; a newer driver is not automatically the best choice for older hardware or Windows versions.
