After investigating, I found that this problem can be solved by a newer setuptools:

Is this OK for pyusb project?
I am not familiar with Python, but I think this dependency should be automatically resolved when pip install pyusb is run.
On the other hand, if pyusb has already dropped Python 2 support, a newer release to Python 2 seems strange, so I am not sure if a bug fix release to Python 2 is correct.
