  27 # Knowledge from customer:
  28 # Devices with OID_END=38 are 12 port power switches with two powerbanks.
  29 # Means each powerbank has 6 outlets. Here we can use ChanStatus in order
  30 # to find out if one powerbank is enabled/used.
  31 #
  32 # Device with OID_END=19 is a simple switch outlet: 1 Port and 1 powerbank
  33 # Once it's plugged in, the state is "on". Thus we use PortState in
  34 # discovering function.
