First of all you need some technical background about USB, hardware and software. With USB there are no Rx/Tx lines, just "one line" over two wires with differential electric transmission.

About your initial question the response is that you cannot write a pure Java implementation. You have to interact with the driver, which is written in C, so you will have to use JNI.
