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. -- Xiaofan ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
