Because you've redirected stdout to a file, the printf()'s that enum-devices
use to output the information are being fully buffered, rather than line
buffered as when it outputs to the terminal. I'm guessing that there's
a bus that supports removable devices (e.g. USB) on your system so 
enum-devices will never terminate and you'll never get the tail end of
the buffered output flushed by the closing of the stream.

What you need to do is direct the output to something that the stream I/O
code in libc will treat as line buffered and then send that to a file
or whatever - for example, a psuedo-tty. You could use the "script" command
at the shell command prompt before running enum-devices. From code, checkout
the forkpty() or openpty() functions.
