Hello,

I have a custom board based on imx8mini. It is supplied from USB type C connecting it to a computer.
How can I know if the custom board has been connected to port 3.0 or port 2.0 of the computer?

Regards,

Josu.

Hello Josu,

Many computer manufacturers do not clearly mark USB port versions. Use the Device Manager to determine if your computer has USB 1.1, 2.0, or 3.0 ports:

1. Open the Device Manager.
2. In the "Device Manager" window, click the + (plus sign) next to Universal Serial Bus controllers. You will see a list of the USB ports installed on your computer.
   • If your USB port name contains "Universal Host", your port is version 1.1.
   • If the port name contains both "Universal Host" and "Enhanced Host", your port is version 2.0.
   • If the port name contains "USB 3.0", your port is version 3.0.
