I keep trying to clean things up and needing std::strings. Might as well just do this now. usb_linux_client.c is going to stay as C because GCC isn't smart enough to deal with the designated initializers it uses (though for some reason it is in C mode). The Darwin files are staying as C because I don't have a way to test that they build. The Windows files are staying as C because while I can actually build for them, it's slow and painful.
