The proper solution uses ctypes.util.find_library, here is a dump from
Linux and one from MacOS:

mkarcher@aquila:~$ python
Python 2.5.4 (r254:67916, Nov 19 2009, 22:14:20) 
[GCC 4.3.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from ctypes.util import *
>>> print find_library("usb-1.0")
libusb-1.0.so.0
>>> 

minimac2:~ zedv$ python
Python 2.6.4 (r264:75706, Feb 4 2010, 14:41:35) 
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from ctypes.util import *
>>> print find_library("usb-1.0")
/opt/local/lib/libusb-1.0.dylib
>>>
