Hello,

I am having problems installing libusb and PyUSB for Cygwin.
Based on the README file of pyusb, I follow the steps:

-download and execute libusb-win32-filter-bin-0.1.12.1.exe from
http://libusb-win32.sourceforge.net

$ "/cygdrive/c/Program Files/LibUSB-Win32/bin/testlibusb.exe"
Dev #0: 0000 - 0000
 Dev #1: Maxtor   - Basics Desktop
  Dev #2: 046D - 08B0

#libusb seems to work


-install cygwin

$ cp /cygdrive/c/Program\ Files/LibUSB-Win32/lib/gcc/libusb.a /usr/lib/
$ cp /cygdrive/c/Program Files/LibUSB-Win32/src/src/usb.h /usr/include/

-download http://sourceforge.net/projects/pyusb
$ tar -xvzf pyusb-0.4.1.tar.gz
$ cd pyusb-0.4.1
$ python setup.py install
running install
running build
running build_ext
running install_lib
running install_egg_info

So, the installation seems to work.
However, I try with:

$ cd /usr/lib/python2.5/site-packages/
$ echo "import usb" >test.py
$ python test.py
Traceback (most recent call last):
  File "test.py", line 1, in <module>

   import usb
ImportError: No such file or directory


Using ldd.sh for cygwin here: http://lassauge.free.fr/cygwin/archive.htm
$ ldd.sh /usr/lib/python2.5/site-packages/usb.dll
C:\cygwin\lib\python2.5\site-packages\usb.dll
  C:\cygwin\bin\cygwin1.dll
   C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\KERNEL32.dll
       C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\RPCRT4.dll
       C:\WINDOWS\system32\Secur32.dll
Error: could not find cygusb0.dll
 C:\cygwin\bin\libpython2.5.dll

It has a problem finding "cygusb0.dll".
What can be the problem?


Best regards,
