/**
 * This is a modified version of detect.c example from libmtp 1.1.8.
 * All it does is to list all the raw devices, without connecting
 * (which sometimes can cause hang). 
 * 
 * It is meant to be used as a replacement of "simple-mtpfs -l".
 * This will provide compatible list (ie devices are listed in the same
 * order) but much more detailed information (USB ids, USB busids)
 * than just the device name and vendor.
 * 
 * \file detect.c
 * Example program to detect a device and list capabilities.
