Download Bu-353s4 Windows 11: G Star Iv Gps Driver

Before downloading drivers, you must understand what you own. Confusion between the BU-353 (legacy SiRF Star III), the BU-353S4 (current SiRF Star IV), and clones is the #1 reason for driver failure.

    How to Download and Install G-Star IV GPS (BU-353S4) Drivers on Windows 11 G Star Iv Gps Driver Download Bu-353s4 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.

    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.

    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. Check Windows 11 bitness (Settings → System →
