GL850G USB Chip Stuck in Reset Mode: Causes and Fixes

The GL850G USB chip is widely used in USB hubs and devices to manage multiple USB connections. However, like any hardware, it can sometimes encounter issues, including getting stuck in a reset mode. This can cause your USB ports to malfunction, making it difficult or impossible to use connected devices. Let's break down the possible causes and provide clear, step-by-step solutions to resolve this issue.

Causes of GL850G USB Chip Stuck in Reset Mode

Driver Conflicts or Corruption: One of the most common causes of this issue is a conflict between Drivers or a corrupted driver installation. When Drivers are outdated or incompatible with the operating system, the USB chip can fail to initialize properly, causing it to get stuck in a reset state. Hardware Issues: Physical damage to the GL850G chip or the motherboard can cause it to malfunction. Overheating, Power surges, or a faulty power supply can affect the chip’s performance. Firmware Problems: If the firmware of the GL850G is outdated or corrupted, it can lead to erratic behavior, such as getting stuck in reset mode. Firmware controls the basic functions of the chip, and without the correct version, the chip may fail to operate correctly. Power Supply Problems: Insufficient power can cause the USB chip to malfunction. This could be due to an unstable or inadequate power supply from the computer or the USB hub itself, which can cause the chip to reset continuously. Operating System Issues: Sometimes, the operating system can prevent proper communication between the USB chip and the system, especially after updates or changes to the USB settings. This can trigger the chip to enter a reset state.

Step-by-Step Solutions to Fix the GL850G USB Chip Stuck in Reset Mode

Solution 1: Update or Reinstall USB Drivers Open Device Manager: Press Windows + X and select Device Manager. Locate the USB Hub: Expand the “Universal Serial Bus controllers” section. Find the GL850G USB Hub (it may show as a "USB Root Hub" or something similar). Uninstall and Reinstall the Driver: Right-click on the GL850G USB Hub and choose Uninstall device. After uninstallation, restart your computer. Windows will attempt to reinstall the driver automatically. Alternatively, visit the manufacturer’s website to download the latest driver for the GL850G chip. Solution 2: Check for Firmware Updates Identify the Chip’s Model and Version: Check the device's manufacturer or the USB hub’s specifications to find out the firmware version of the GL850G. Download Firmware Updates: Visit the manufacturer’s official website or a trusted third-party website to find the latest firmware updates for your chip. Install the Firmware Update: Follow the instructions provided by the manufacturer for updating the firmware. This might involve connecting the device to a special software or using a USB programmer. Solution 3: Inspect Hardware for Damage Disconnect All USB Devices: Unplug any devices connected to the USB ports and turn off the computer. Visually Inspect the Chip: If possible, visually inspect the USB hub and the GL850G chip for any signs of physical damage or overheating. Look for burnt components or damaged pins. Replace if Necessary: If you notice damage, you may need to replace the USB hub or the GL850G chip. This could involve purchasing a new hub with the same chip. Solution 4: Verify Power Supply Ensure Proper Power Supply: If you're using a powered USB hub, ensure that it is connected to a reliable power source. If you're using a laptop, make sure it's plugged into the charger. Try a Different USB Port: If the chip is part of a motherboard USB hub, try plugging the device into a different USB port to rule out any issues with a specific port. Solution 5: Troubleshoot Operating System Issues Run Windows Troubleshooter: Open Settings, go to Update & Security, and select Troubleshoot. Choose Additional troubleshooters and run the Hardware and Devices troubleshooter. Reset USB Settings: In Device Manager, right-click each USB device and select Uninstall. After restarting your computer, Windows will reinstall the USB drivers. Check for Windows Updates: Ensure that your operating system is up-to-date by checking for new updates under Settings > Update & Security > Windows Update.

Preventing Future Issues

Regularly Update Drivers and Firmware: Always keep your drivers and firmware updated to prevent conflicts and improve overall performance. Avoid Overloading USB Ports: If you're using multiple USB devices, ensure your computer or hub can supply enough power to each device. Proper Ventilation: Ensure your devices are well-ventilated to prevent overheating of the USB hub and chip.

By following these steps, you should be able to identify the root cause of the GL850G USB chip being stuck in reset mode and apply the appropriate fixes. If the issue persists after all these steps, it may indicate a deeper hardware failure requiring professional repair or replacement of the USB hub or motherboard.
