That is not possible.

USB is a protocol with many(!!) layers.

They should be understood to be used best.

That said, in Linux, you can try using the hidraw API. There isn't a
lot of documentation even in the kernel sources, but use google and
you'll find some. One particular project is about the PS3 controller.
It has some source code which should be easy to understand.
