Hi. I am trying to connect to a USB device running PyUSB 1.0.0-a1, libusb-win32 1.2.4.0, under a Windows 7(x86) administrator and python 2.7.1. I have created and installed a .inf file from libusb. Whenever I try to run a script to read the device, I get an exception reading: WindowsError: exception: access violation reading 0x00000018
If I try to write to the device, I get: AttributeError: 'NoneType' object has no attribute 'bmAttributes' My code is simply: import usb.core as core usbDevice = core.find() usbDevice.set_configuration() rawRead = usbDevice.read(0x81, 5, 0, 100) print(rawRead) Thank you for any help. ------------------------------------------------------------------------------ Simplify data backup and recovery for your virtual environment with vRanger.
