while trying to pip install pyusb on Macbook Pro OS X Mavericks I get the following error:

XXXXXXXXXXXXXXXX:~ xxxxxxxxxxxxxxxxx$ pip install pyusb
Downloading/unpacking pyusb
Could not find a version that satisfies the requirement pyusb (from versions: 1.0.0a2, 1.0.0a2, 1.0.0a3, 1.0.0a3, 1.0.0b1)
Cleaning up...
No distributions matching the version for pyusb
Storing complete log in /Users/xxxxxxxxxxxxxxx/.pip/pip.log

Does anyone know what to do?

Is there a way to see what pyusb versions are available from pip? Can you force to install e.g. 1.0.0b1?

This allows for non-stable versions (1.0.0a2, 1.0.0a2, 1.0.0a3, 1.0.0a3, 1.0.0b1) to be installed.
