I thought of removing this functionallity to make it easier, but thought that later when multiple hubs and/or functions were desired, it would already be half way there. - Currently, this code is quite messy. This is for all of the debugging I have been doing. Many printf()'s here and there. - My purpose of coding this emulation was/is to learn about the USB. It has been a challenge, but I have learned a lot. - - - - If I forget, there are a lot of BX_INFO's that can be changed to BX_DEBUG's. */ // Define BX_PLUGGABLE in files that can be compiled into plugins.
