I got usbview.exe from here ... maybe you can use Win32::CtrlGUI and Win32::Clipboard and do: 
LOOP:
  down arrow       # move to next item in the tree in the left pane
  TAB              # move focus to right pane
  ctrl-a           # select all (though it might auto-highlight everyt
+hing already)
  ctrl-c           # copy to clipboard
  parse clipboard using Win32::Clipboard to look for what you need
  TAB              # move focus back to left pane
end loop when ???? get repeated text?? after 100 "down's"??
