Steps:
Open Device Manager. Expand Universal Serial Bus controllers. Right-click each USB Root Hub > Properties. Go to the Power Management tab. Uncheck "Allow the computer to turn off this device to save power." Click OK and restart your computer. Step 5: Test with Different DevicesAction: Identify if the problem is with specific devices.
Steps:
Connect different USB devices (e.g., mouse, keyboard, flash drive) one by one to the hub. Note which devices fail to work and if the issue is consistent. Step 6: Reduce Hub LoadAction: Avoid overloading the hub with too many high-power devices.
Steps:
Disconnect unnecessary devices. Connect high-power devices (like external hard drives) directly to the computer if possible. Use a powered USB hub if needed to increase capacity. Step 7: Test on Another ComputerAction: Determine if the issue is with your computer or the hub.
Steps:
Connect the USB2517I-JZX to a different computer. Check if the issue persists. Step 8: Check for Operating System UpdatesAction: Ensure your computer's OS is up to date.
