@Muhammed Zakir:
It is working good for me. Was it broken after you made an commit(if any)?
In my case under Win7 64 bit btchip-python is unstable, can't be used together with Electrum.
Did you use libusb-win32-bin-1.2.6.0?
Did you compile cython with Microsoft Visual C++ VCForPython27?
Or you used a MinGW environment?
Yes, I use libusb but don't remember the version and I installed Cython using Python setup.py command and it used Visual C++.
