title: Connecting odoo with zk device
body: <p>I am trying to connect odoo with zk device (ZKTeco model K40).I installed zklib to download attendance info from the device.
  I tried the following code:</p>
  
  <pre><code>import sys
  import time
  import zklib
  from zklib 
  import zkconst
  zk = zklib.ZKLib("192.168.1.201", 4370)
  conn=zk.connect()
  </code></pre>
  
  <p>When I print conn, its value is False, even when I am sure that the connection parameters are well. I tried pyzk library too, but I had the same connection problem. Then, I tried to connect with another zksoftware (ZKTime) and it connected. 
  What else can I do to connect odoo 8 with zk device? </p>
