I had tried to use the code above. It still not working, I am getting 
the same error message:
irb(main):004:0> avmc.FindAllAvmc(dev)
WIN32OLERuntimeError: _invoke
    OLE error code:0 in <Unknown>
      <No Description>
    HRESULT error code:0x80020005
      Type mismatch.
        from ./avmc.rb:39:in `_invoke'
        from ./avmc.rb:39:in `FindAllAvmc'
        from (irb):4

Thanks for you reply. I will try to install the new ruby 1.9 on other 
machine and try again. I had been using this dll on C# and python. Both 
is working fine. May be I also need to look into the source code...but I 
am really not familiar with windows com dll programming. It seems like 
too many specification on it.
