Subject: troubles with nested hashes

i'm new to ruby and not that great a programmer so bear with me.  i'm
trying to dynamically populate a nested hash.  below is the structure of
what i'm trying to populate

devices = {
   'macaddr' => {
      'packets' => '',
      'ip' => '',
      'name' =>
   }
}

macaddr is my unique identifier and it will have certain properties
(packets, ip, and name).  just so you know i'm reading the information
over the network, which is simply a comma separated line of text, and
putting that into an array like below.

Csv.parse(whatever) do |line|
   devices['macaddr'] = line[0]
   devices['macaddr']['packets'] = line[1]
end

it fails here => devices['macaddr']['packets'] = line[1]

i also tried another approach, instead of defining the nested hash i
used the code below.

devices = Hash.new{|h,k| h[k]=Hash.new(&h.default.proc)}
Csv.parse(whatever) do |line|
   devices['macaddr'] = line[0]
   devices['macaddr']['packets'] = line[1]
end

it still fails on the same line, any clue on what i'm doing wrong?  also
is this the best approach?  thanks.
