how to fix my usb connection if no conection

Hi Morris Garrett,

Thanks for reaching out to Microsoft Q&A Forum. I understand that when you connect a USB device to your Windows 11 laptop, nothing appears or is detected.

Please make sure you already tried the Q&A Assist steps. In addition, please try the following.

To help narrow this down:

1. When you connect the USB device, do you see any change at all in Device Manager (for example, a device appearing briefly or an Unknown device)?
2. Does the USB device show any power activity, such as an LED light turning on?

In the meantime, you can try these steps:

1, Restart Windows with Fast Startup disabled

• Open Control Panel
• Select Power Options
• Select Choose what the power buttons do
• Select Change settings that are currently unavailable
• Uncheck Turn on fast startup
• Shut down the laptop and power it back on

2, Check USB power management settings

• Open Device Manager
• Expand Universal Serial Bus controllers
• Right‑click each USB Root Hub and select Properties
• Open the Power Management tab
• Uncheck Allow the computer to turn off this device to save power
• Select OK and repeat for all USB Root Hub entries

3, Check for hidden or disabled devices

• Open Device Manager
• Select View
• Select Show hidden devices
• Expand Universal Serial Bus controllers and Disk drives
• If you see any disabled devices, right‑click and select Enable

4, Check BIOS/UEFI USB settings

• Restart the laptop and enter BIOS or UEFI setup
• Confirm USB ports and Legacy USB support are enabled
• Save changes and exit

5, Perform a Windows hardware scan

• Open Device Manager
• Select Action
• Select Scan for hardware changes
• Plug in the USB device again and check if it appears

Hi, I'm John! I will help you with this.

To help narrow down the issue:

1. What USB device are you trying to connect (flash drive, phone, external drive, etc.)?
2. Does the device work on another computer?
3. Have you tried a different USB port on your laptop?

In the meantime, if you haven’t already:

• Plug in the USB device.
• Press and hold the Power button for about 10 seconds to force shutdown.
• Wait for 30 seconds.
• Turn the laptop back on while the USB is still plugged in.
• This can help reset the USB controller.

After it boots up, does the USB show up?

If the issue persists, please provide more details by answering my questions.

Try these steps in order on the Windows 11 laptop:

1. Check the USB device and cable

• Make sure the device has power (if it has a power switch or its own power supply, turn it on and plug in power).
• Inspect the USB cable and connector for damage.
• If it’s battery-powered (for example, a wireless mouse/keyboard receiver), make sure the batteries are fresh.

2. Reconnect the device

• Unplug the USB device.
• Wait 10–15 seconds so Windows can unload the driver.
• Plug the device back into the same port and wait a few seconds.

3. Try different ports and remove hubs

• Plug the device into a different USB port on the laptop.
• If using a USB hub, make sure the hub has power.
• If it still does not work, remove the hub and plug the device directly into the laptop.

4. For USB‑C ports (if the laptop has them)

• If using a USB‑C hub or adapter, disconnect it and plug the USB‑C device directly into the laptop.
• Unplug the USB‑C device, then shut down Windows: Start > Power > Shut down.
• After shutdown, wait 10 seconds, then power on the laptop.
• When Windows is fully loaded, plug the USB‑C device back in.
• Use the cable that came with the device; not all USB‑C cables support all features (data, power, video).

5. Check Device Manager for USB controller issues

• Open Device Manager (press Windows key, type Device Manager, press Enter).
• Scroll down and expand Universal Serial Bus controllers.
• If any USB controller shows a warning icon, right‑click it and select Uninstall device.
• Repeat for each USB controller under Universal Serial Bus controllers.
• Restart the laptop. Windows will reinstall the USB controllers automatically.
• After restart, plug in the USB device again and check if it is detected.

6. Update Windows, drivers, and firmware

• Open Settings > Windows Update and install all available updates.
• If using a Surface device, open the Surface app, go to Help & support, and select Check for updates to ensure the latest drivers and firmware are installed.

If the device still does not appear after these steps, test the USB device on another PC. If it also fails there, the device itself may be faulty.
