CP2108-B03-GMR Not Recognized by Windows? Here's Why and How to Fix It

If you're encountering an issue where your CP2108-B03-GMR device is not recognized by Windows, don't worry. There could be a number of reasons causing this problem. Below, we will walk you through the possible causes and provide step-by-step solutions to help you resolve this issue.

Possible Causes for CP2108-B03-GMR Not Being Recognized:

Missing or Corrupted Drivers The most common cause of a device not being recognized is the absence or corruption of Drivers . Incorrect USB Port or Cable Sometimes, using a faulty USB port or cable can prevent the device from connecting properly. Device Conflict There could be a conflict with another connected device that is preventing the CP2108-B03-GMR from being recognized. Outdated Windows OS An outdated Windows operating system might not support the latest drivers or firmware required by the device. Power Supply Issues If the device isn't receiving enough power, it might fail to be recognized by the computer.

Step-by-Step Troubleshooting and Fixes:

Step 1: Check the USB Port and Cable Test different USB ports: Try connecting the device to another USB port on your computer, preferably a port directly on the computer rather than a hub. Test with a different USB cable: If possible, use a different USB cable to rule out any issues with the cable itself. Step 2: Update or Install the Correct Drivers

Go to the Silicon Labs website: The CP2108-B03-GMR is manufactured by Silicon Labs, so you can find the latest drivers for this device on their website.

Visit the Silicon Labs download page. Select the appropriate driver for your system and download it.

Install the driver:

Open the downloaded file and follow the on-screen instructions to install the driver. After installation, restart your computer.

Check Device Manager:

Right-click on the Start menu and select Device Manager. Under Ports (COM & LPT), check if the CP2108-B03-GMR appears. If the device shows a yellow triangle or an error, right-click on it and select Update Driver.

Step 3: Troubleshoot Device Conflicts Disconnect other devices: If you have multiple USB devices connected, disconnect all of them except for the CP2108-B03-GMR to ensure there is no conflict. Check for other devices in Device Manager: Look for any unknown devices or devices with error symbols. If found, uninstall them by right-clicking and selecting Uninstall device. Step 4: Update Windows Check for Windows updates: Go to Settings > Update & Security > Windows Update. Click Check for updates and install any available updates. Install optional updates: Sometimes, optional updates may include important drivers or bug fixes related to device recognition. Step 5: Test the Power Supply Try another computer: To rule out any issues with the power supply from your current PC, test the device on a different computer. Use a powered USB hub: If you’re using a USB hub, ensure that it is powered. Some devices may require additional power that non-powered hubs can't provide.

Additional Tips to Consider:
