if you are looking to directly build something in low level you can see http://www.beyondlogic.org/ for information about specs...

If you want some examples of code you can look at http://www.libusb.org/wiki/libusb-1.0 ... It's in C though.

If you just want to communicate with the USB in linux, you can just have linux mount it and write to it as a regular drive without having to deal with all the other stuff...
