About USB IOCTL Code.

As Title.
I get the code :220010, 220013,220018,and 220038,
but I don\'t know what is it.
I need the name of Code,like IOCTL_ABORT_PIPE.
Can anyone give me the trick?

I need to chk the IoCode,but some IoCode....I don\'t know it...2D0C10,2D1300..etc

P.S IOCTL_STORAGE_QUERY_PROPERTY is 2D1400
