Hi Lattepandaers,

I am new to Lattepanda board, for now, I am playing with a Lattepanda V1.0.
I found that in my project an extra USB port is required, while I don't have room for an extra USB hub in the hardware case. This project limits the size of the hardware.

So is it possible to convert the Arduino port or other port into a USB one? I notice that the power, which is a micro USB port marked as USB22 on the pcb, may connect to a passive component if I provide power to the board directly. And the Arduino port is marked as USB21. Is it means I can use it as a USB?

If the topic is to convert regular GPIO pins to USB leads, the answer is NO.
There is a USB protocol engine behind the USB D+ D- leads. You'll need that.
