[riteshSTPL]

I have followed all the step as per the guide http://microchipdeveloper.com/iot:ztpk

But kit_provision.py gives me following error

Opening AWS Zero-touch Kit Device
Traceback (most recent call last):
  File "D:\Projects\Liquitech\AtmelAWS\Software\aws-iot-zero-touch-secure-provisioning-kit-master\kit_provision.py", line 147, in <module>
    main()
  File "D:\Projects\Liquitech\AtmelAWS\Software\aws-iot-zero-touch-secure-provisioning-kit-master\kit_provision.py", line 27, in main
    device.open()

    return self.device.open(vendor_id, product_id)
  File "hid.pyx", line 66, in hid.device.open
OSError: open failed

I am getting driver detected with following VID & PID. So i updated in 'mchp_aws_zt_kit.py'. DEVICE_HID_VID = 0x03eb DEVICE_HID_PID = 0x2111 After updating i am getting below error.
