You can locate UsbIo protocol, the prototype is described in UEFI Spec.

You can check it first.

Subject: [edk2-discuss] Communicating with usb devices

Hi All,
I am a newbie in EFI development. Currently I have a requirement of
enumerating attached USB devices, communicating with them and etc.

However, after spending a day, I could not able to crack this thing. i can see
that in MdePkg and MdeModulePkg exists some driver for communicating
with usb devices but i can't figure out how should i use them.

I appreciate it if anyone could give me an example code or something like
that for communicating with usb devcies.

thanks
