I am not so sure why pyusb can not find the backend under Cygwin Python (latest svn). Kind of strange.
I have cygusb0.dll and cygusb-1.0.dll under c:\cygwin\bin and they are the DLL name for libusb-win32 0.1 and libusb 1.0 Windows under Cygwin respectively. I even tried to add 'cygusb0' and 'cygusb-1.0' for the load library function, but it does not seem to work. Maybe Cygwin is a bit special. mc...@acerpc ~/mcu/pyusb/pyusb $ python setup.py install running install running build running build_py creating build creating build/lib creating build/lib/usb copying usb/core.py -> build/lib/usb copying usb/legacy.py -> build/lib/usb copying usb/util.py -> build/lib/usb copying usb/_interop.py -> build/lib/usb copying usb/__init__.py -> build/lib/usb creating build/lib/usb/backend copying usb/backend/libusb01.py -> build/lib/usb/backend copying usb/backend/libusb10.py -> build/lib/usb/backend copying usb/backend/openusb.py -> build/lib/usb/backend copying usb/backend/__init__.py -> build/lib/usb/backend running install_lib running install_egg_info Removing /usr/lib/python2.5/site-packages/PyUSB-1.0.0_a0-py2.5.egg-info Writing /usr/lib/python2.5/site-packages/PyUSB-1.0.0_a0-py2.5.egg-info mc...@acerpc ~/mcu/pyusb/pyusb/tests $ python Python 2.5.2 (r252:60911, Dec 2 2008, 09:26:14) [GCC 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)] on cygwin Type "help", "copyright", "credits" or "license" for more information. >>> import usb.core >>> import usb.backend.libusb10 >>> b=usb.backend.libusb10.get_backend() >>> assert b is not None Traceback (most recent call last): File "<stdin>", line 1, in <module> AssertionError >>> import usb.backend.libusb01 >>> a=usb.backend.libusb01.get_backend() >>> assert a is not None Traceback (most recent call last): File "<stdin>", line 1, in <module> AssertionError -- Xiaofan http://mcuee.blogspot.com ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
