I rebuild the DLL with MSVC2008 and it is now working fine when
using interactive Python.
c:\cygwin\home\mcuee\mcu\pyusb\pyusb\tests>python
Python 2.6.5 (r265:79096, Mar 19 2010, 21:48:26) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import usb.core
>>> d=usb.core.find(idVendor=0xfffe)
>>> d.write(1,"Hello")
5
>>> d.read(0x81,5)
array('B', [72, 101, 108, 108, 111])
>>> exit()
But there are a few errors for the tests.
