[MAGEEC] Installing pyusb as per wiki instructions

[Alex J Lennon]

Hi all,

I'm working through a clean install of the power monitoring software as
per the Software Requirements section of the workshop Wiki page here:

http://mageec.org/wiki/Workshop#Software_setup

I ran into some trouble with my standard Ubuntu LTS VM and so tried with
the latest Ubuntu 13.10 but it gives the same error:

~$ sudo pip install pyusb docopt
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...

I found what I think is the solution with the following which seems to
get it installed:

~$ sudo pip install --pre pyusb docopt
Downloading/unpacking pyusb
  Downloading pyusb-1.0.0b1.tar.gz (44kB): 44kB downloaded
  Running setup.py egg_info for package pyusb

Downloading/unpacking docopt
  Downloading docopt-0.6.1.tar.gz
  Running setup.py egg_info for package docopt

Best Regards,

Alex
