strace is likely to provide some information about why (or, at least,
where) the program hangs.

If you want more information about libusb and threads, this may be
interesting:

  http://libusb.sourceforge.net/api-1.0/mtasync.html

The LIBUSB_DEBUG environment variable can be used to enable message
logging at run-time, as an alternative to explicit use of
libusb_set_debug() during program execution.
