To communicate with your USB devices, your computer needs the correct driver. If you’re facing issues with your USB-Serial Controller D, this always means that the current driver installed is outdated or corrupt. To fix it, you need to update your USB-serial Controller D driver.

How to update your USB-serial controller d driver

There are two ways you can update your USB-serial Controller D driver:

  • Option 1 – Manually
    • You’ll need some computer skills and patience to update your drivers this way, because you need to find exactly the right the driver online, download it and install it step by step.
  • Option 2 – Automatically (Recommended)
    • This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.

Option 1 – Manually

To update your USB-Serial Controller D driver manually, first you’ll need to go to Device Manager to update the driver automatically. If Windows fails to find any updates, then head to the manufacturer’s official website to download the exact driver for your device and install it manually.

Step 1: Update your USB-Serial Controller D driver via Device Manager

  1. Open Device Manager.
    • For Windows 10: Right click Start and select Device Manager.
    • For Windows 10, 8.1, 7: Press the Windows logo key + R at the same time, then enter devmgmt.msc in the Run box and hit Enter.
  2. Expand Other devices and right click your USB-Serial Controller D and select Update driver.
  3. Select Search automatically for updated driver software. Windows will find the latest driver and install it for you automatically if it finds one.

However, Windows cannot always find the latest driver for you, so you can head to the manufacturer’s website to download the latest driver and manually install it or do it automatically in Option 2.

Step 2: Download the USB-Serial Controller D driver from the manufacturer’s website

  1. Head to the official website of the manufacturer and download the latest driver.
  2. Double click the downloaded driver file and follow the on-screen instructions to finish the install.
  3. Restart your computer for the changes to take effect.
Note: If you don’t know the manufacturer, you can go to Device Manager for more information.
– Expand Other devices and right click USB-Serial Controller D > Select Properties.
– Under the Driver tab, you can view its driver provider, driver version and date etc.

Option 2 – Automatically

    Note: You can do it for free if you like, but it’s partly manual.
  4. Restart your computer for the changes take effect.
