USB hubs are commonly used to expand the number of available ports on laptops and desktops, especially on modern systems with limited USB connectivity. When a USB hub is not working properly or operates very slowly in Windows 11, connected devices may disconnect randomly, fail to be detected, or transfer data at extremely low speeds.
This issue can be caused by power limitations, outdated USB drivers, incorrect power management settings, incompatible hub hardware, or Windows 11 USB controller problems. In many cases, the hub itself is functional, but Windows is not managing power or drivers correctly.
Fixing a USB hub that is not working or running slow in Windows 11 involves checking power delivery, updating drivers, and adjusting USB and power settings. The steps below explain how to restore normal USB hub functionality and performance.
How to Fix USB Hub Not Working or Slow in Windows 11
The methods in this section focus on resolving USB power issues, driver conflicts, and system settings that commonly affect USB hubs. Apply the steps in order and test the USB hub after each method.
Restart the system where instructed so changes take effect properly.
1. Check USB Hub Power and Connection
Power issues are the most common cause of USB hub problems.
- Disconnect the USB hub from the computer.
- Unplug all devices connected to the hub.
- If using a powered USB hub, ensure the external power adapter is connected.
- Reconnect the hub directly to the computer.
- Plug in one device at a time and test performance.
Unpowered hubs may struggle to supply enough power for multiple devices.
2. Try a Different USB Port on the Computer
Faulty or slower ports can affect hub performance.
- Disconnect the USB hub.
- Plug it into a different USB port on the computer.
- Prefer USB 3.0 or USB-C ports if available.
- Avoid front-panel ports on desktops if possible.
Some ports provide better power and bandwidth than others.
3. Restart the Computer
Temporary USB controller issues can cause slow or failed detection.
- Save all open work.
- Restart the computer.
- Reconnect the USB hub after Windows fully loads.
A restart resets USB controllers and device enumeration.
4. Update USB and Chipset Drivers
Outdated drivers can cause USB speed and detection issues.
- Press Windows + X and open Device Manager.
- Expand Universal Serial Bus controllers.
- Right-click each USB Root Hub and select Update driver.
- Expand System devices and update chipset-related drivers.
- Restart the system after updates.
Updated drivers improve USB stability and performance.
5. Disable USB Power Saving Settings
Power management can slow down or disable USB hubs.
- Open Device Manager.
- Expand Universal Serial Bus controllers.
- Right-click USB Root Hub and select Properties.
- Open the Power Management tab.
- Uncheck Allow the computer to turn off this device to save power.
- Click OK.
- Repeat for all USB Root Hub entries.
- Restart the computer.
Disabling power saving prevents USB disconnects and slowdowns.
6. Change Windows Power Plan Settings
Aggressive power plans can limit USB performance.
- Open Control Panel.
- Go to Power Options.
- Select High performance or Best performance.
- Click Change plan settings.
- Select Change advanced power settings.
- Expand USB settings.
- Disable USB selective suspend.
- Apply changes and restart.
This ensures consistent USB power delivery.
7. Check USB Hub and Device Compatibility
Not all hubs work well with all devices.
- Test the USB hub with a different computer.
- Test devices directly on the computer without the hub.
- Avoid mixing high-power devices such as external drives and webcams on unpowered hubs.
Compatibility issues can cause speed drops and detection failures.
8. Update Windows 11
USB-related bugs are often fixed through updates.
- Open Settings.
- Go to Windows Update.
- Click Check for updates.
- Install all available updates.
- Restart the computer.
Updates improve USB controller behavior and device support.
9. Check USB Speed Limitations
Older hubs may limit performance.
- Confirm whether the hub supports USB 3.0 or USB 2.0.
- Understand that USB 2.0 hubs cap speeds even when connected to USB 3.0 ports.
- Upgrade to a USB 3.0 or USB-C hub if higher speeds are required.
Hub hardware directly affects data transfer rates.
10. Replace the USB Hub if Necessary
Hardware failure can cause persistent issues.
- Test with another USB hub.
- Use a powered hub for multiple devices.
- Choose hubs from reputable manufacturers with Windows 11 support.
Faulty hubs often cause intermittent or slow performance.
Final Thoughts
A USB hub not working or running slow in Windows 11 is usually caused by power limitations, driver issues, or aggressive power-saving settings rather than a Windows defect. By updating drivers, disabling USB power saving, and ensuring proper power delivery, most USB hub problems can be resolved quickly.
