On Linux, this is easy: the usbfs kernel interface exposes a file descriptor

platform, you can emulate this using an internal library thread to reap I/O as
necessary, and a pipe() with the main library to raise events. The file
descriptor of the pipe can then be provided to libusbx as an event source.
