The work-around seems to speel out the full name ".dll".
Maybe this can be done in pyusb.
In the bug report, there is a test script attached.
http://bugs.python.org/file27618/ct_test.py
import sys
import os
import ctypes.util
lookup_path = "C:\\Windows\\system32"
dll_file = os.path.join(lookup_path, "OpenAL32.dll")
print("Python build: %s" % sys.version)
print("Path '%s' exists in $PATH: %s" % (lookup_path, lookup_path in
os.environ["PATH"].split(os.pathsep)))
print("File '%s' exists: %s" % (dll_file, os.path.exists(dll_file) and
os.path.isfile(dll_file)))
print("ctypes says for '%s': %s" % ("OpenAL32.dll",
ctypes.util.find_library("OpenAL32.dll")))
--- this works.
print("ctypes says for '%s': %s" % ("OpenAL32",
ctypes.util.find_library("OpenAL32")))
--- this does not work.

This code when run in python 2.7.4 raises an exception with unicode text as
data.

How can the user decide in your method? I don't see it.

I do prefer using pip to manage Python package on Debian / Ubuntu / whatever / .. OS X. The main reason is actually to use several versions of Python modules on the same host, thanks to virtualenv. It is far more versatile and flexible, especially with Python modules that evolve far more quickly than Debian official repositories. PyUSB is actually packaged on PyPi btw. [OT] "libusb-1.0-0" on Debian is now using libusbx, which is quite confusing.
