Hi Wander, I have been running my software on different computers (not an OS issue since I have working and non- working software on different OSs) The software which is the java code calling an executable python code (which uses the usb) on some of the systems runs fine. On some others I get this message:
ERROR:usb.backend.libusb10:Error loading libusb 1.0 backend Traceback (most recent call last): File "Manager\build\pyi.win32\Manager\outPYZ1.pyz/usb.backend.libusb10", line 600, in get_backend File "Manager\build\pyi.win32\Manager\outPYZ1.pyz/usb.backend.libusb10", line 160, in _load_library OSError: USB library could not be found 2011-11-15 18:23:59,220 ERROR:usb.backend.openusb:Error loading OpenUSB backend Traceback (most recent call last): File "Manager\build\pyi.win32\Manager\outPYZ1.pyz/usb.backend.openusb", line 598, in get_backend File "Manager\build\pyi.win32\Manager\outPYZ1.pyz/usb.backend.openusb", line 148, in _load_library OSError: USB library could not be found 2011-11-15 18:23:59,220 ERROR:usb.backend.libusb01:Error loading libusb 0.1 backend Traceback (most recent call last): File "Manager\build\pyi.win32\Manager\outPYZ1.pyz/usb.backend.libusb01", line 558, in get_backend File "Manager\build\pyi.win32\Manager\outPYZ1.pyz/usb.backend.libusb01", line 180, in _load_library OSError: USB library could not be found I have libusb-win32 installed on every computer. Why is it that libusb1.0 is required even though that libusb0 exists. Wasn't it said that at least one of these needs to be installed? Please help since I can not figure out what other possibility I can think of to resolve this issue.
