It also depends what version of FreeBSD.  For example, in FreeBSD 4, kqueue
was non-functional with USB serial devices.  I ran into that exact problem
with kqueue when porting my event library.  Problems like that can make life
difficult for a library author; having a special case for one kind of handle
is a pain, to the point of leading to comments like this.

Of course, in this case the best thing to do is to ask the author, and to
see if the situation has changed.
