How can I tell if USB 2 or 3?

Determine the version of USB ports on your computer

1. If your USB port name contains "Universal Host", your port is version 1.1.
2. If the port name contains both "Universal Host" and "Enhanced Host", your port is version 2.0.
3. If the port name contains "USB 3.0", your port is version 3.0.
