Why Does My USB 3. X Hub Work at USB 2. X Speed

Troubleshooting

수정일November 11, 2026

If your USB 3.x Hub appears to operate at USB 2.x speeds, the issue may involve the USB connection, host drivers, operating system settings, or how diagnostic tools report the connection. This guide explains how to verify the connection speed and restore USB 3.x performance.

Key Takeaways

A USB 3.x Hub may display both USB 2.x and USB 3.x connections simultaneously due to backward compatibility.
Reconnecting the hub or connecting another USB 3.x device may restore the correct USB 3.x link speed.
Outdated motherboard or chipset drivers can prevent proper USB 3.x operation.
BIOS configuration issues may affect USB performance and detection.
USBTreeView results should be interpreted carefully, as USB 2.x entries may appear even when USB 3.x is functioning correctly.

Troubleshooting

Step 1. If the USB Hub model is UH720, UH700, or UH400, unplug the USB cable connecting the hub to the PC, then reconnect it quickly.

Step 2. On Windows 10 or Windows 11, try connecting another USB 3.0 device first, then reconnect the USB Hub and check whether the connection speed is restored to normal.

Step 4. Please visit the official motherboard or laptop manufacturer’s website to download and install the latest drivers, especially if you are using Windows 7.

Step 5. If the issue persists, please try resetting the BIOS settings to their default values.
