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.
