How to Download and Install G-Star IV GPS (BU-353S4) Drivers on Windows 11

The GlobalSat BU-353S4 (often referred to as the G-Star IV) is a legendary USB GPS receiver known for its reliability in marine navigation, fleet management, and amateur radio. However, because the hardware predates Windows 11, getting it to talk to your modern PC can be a bit tricky. Locate the Official Driver : The first step

If you’ve plugged in your device and seen the dreaded "Yellow Exclamation Mark" in Device Manager, follow this guide to get your GPS back on the map. 1. Understanding the Hardware

The BU-353S4 uses a Prolific PL2303 USB-to-Serial chipset. Windows 11 is notoriously picky about Prolific drivers because many older "Type HXA" chips are no longer supported by Prolific’s newest drivers. To make this work, you usually need a specific version that maintains compatibility with the S4 hardware. 2. Where to Download the Official Driver

Avoid third-party "driver updater" websites, which often bundle malware. There are two reliable sources:

GlobalSat Official Support: Visit the GlobalSat WorldCom support page. Search for "BU-353S4" to find the Windows driver package.

Prolific Technology Inc: Since the internal chip is Prolific, you can download the "PL2303 Windows Driver Installer" directly from Prolific’s website. 3. Step-by-Step Installation Guide for Windows 11 Step A: Clean the Old Drivers Disconnect your BU-353S4 from the USB port. Right-click the Start button and select Device Manager. Go to View > Show hidden devices.

Look under Ports (COM & LPT). If you see an "Unknown USB Device" or an older Prolific entry, right-click it and select Uninstall device. Check the box for "Attempt to remove the driver for this device." Step B: Run the Installer

Download the PL2303_Prolific_DriverInstaller_v4.x.x (or the version provided by GlobalSat). Right-click the installer and select Run as Administrator.

Follow the prompts and Restart your computer when finished. This step is vital for Windows 11 to register the serial port mapping. Step C: Plug and Verify Plug your G-Star IV into a USB port. Open Device Manager again and expand Ports (COM & LPT).

You should now see: Prolific USB-to-Serial Comm Port (COMx). Note the number (e.g., COM3). 4. Troubleshooting: "This Device Cannot Start (Code 10)"

If you see Code 10 or "Please contact your supplier," Windows 11 has likely automatically updated your driver to a version that doesn't support your specific chip revision. The Fix: Right-click the driver in Device Manager > Update driver. Select Browse my computer for drivers.

Select Let me pick from a list of available drivers on my computer.

Choose an older version (e.g., version 3.8.x or 3.2.x) from the list. Often, the 2014 or 2015 versions work best for the BU-353S4 on Windows 11. 5. Testing Your GPS Signal

Once the driver is installed, your GPS needs a clear view of the sky. Download the GPSInfo Utility from the GlobalSat website.

Open the utility, select your COM Port, and set the Baud Rate to 4800.

Click "Start." You should see NMEA data (text strings) scrolling and, eventually, your lat/long coordinates.

By following these steps, your BU-353S4 should work perfectly with navigation software like OpenCPN, Google Earth Pro, or ESRI ArcGIS on Windows 11.

5. Installation Procedure (assumes CP210x or PL-2303 driver)

1. Download correct driver (x64 for 64-bit Windows 11).
2. Unblock installer if downloaded from Internet: right-click → Properties → Unblock (if present).
3. Run installer as Administrator and follow prompts.
4. Reboot system if prompted.
5. Plug the GPS device into a USB port; allow Windows to finish driver installation.
6. Confirm COM port assignment in Device Manager under “Ports (COM & LPT).”

If Windows driver signature enforcement blocks installation:

• Use official signed drivers; avoid disabling signature enforcement unless necessary.
• If necessary for testing, temporarily disable driver signature enforcement (advanced troubleshooting) and reinstall, then re-enable enforcement.

Step 3: Install the Driver

1. Disconnect the BU-353S4 from your PC.
2. Run the downloaded installer as Administrator.
3. Follow the on-screen prompts and restart your PC if prompted.
4. Reconnect the GPS receiver.

9. References & Resources

• Silicon Labs CP210x drivers and documentation (for CP2102-based devices).
• Prolific PL-2303 drivers and support pages.
• Windows 11 driver signing and installation guidance from Microsoft.

Step 4 – Test the GPS

Use a free GPS utility like u-blox u-center, Visual GPS, or HyperTerminal (or PuTTY) to verify NMEA data output:

• Baud rate: 4800 (default) or 115200 depending on configuration
• Data bits: 8, Parity: None, Stop bits: 1

If you see $GPGGA, $GPRMC sentences, your G Star IV GPS driver is working correctly on Windows 11.

Part 7: Frequently Asked Questions

Q: Is the G Star IV the same as SiRFstarIV? Yes. "G Star IV" is a marketing name used by GlobalSat and other OEMs. The chipset is the SiRFstarIV (CSR/SiRF).

Q: Does Windows 11 automatically download the driver via Windows Update? Rarely. Windows Update may install a generic "USB Serial Device" driver which does not allow GPS apps to read NMEA sentences. You must manually install the CP210x VCP driver.

Q: My device says "BU-353" without the "S4". Will this guide work? No. The original BU-353 uses the SiRF Star III chipset and usually requires the older Prolific PL-2303 driver. That driver is incompatible with Windows 11. You need a new GPS.

Q: Why do I need a COM port? I thought GPS was plug-and-play. GPS receivers are serial devices. They do not appear as a "GPS" in Windows. They appear as a virtual COM port. Your navigation software (OpenCPN, Google Earth Pro, Delorme Street Atlas) must open that COM port and read the data stream.
