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

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

You can check it first.
