I recently purchased USB to serial converter for my power book g4, but the disc that it comes with is small, like a gamecube game. Since there's no try to put it in and a I need to install this or the cord won't work, how can I do it? Do I just stick it in or is there an alternative *insert sexual joke here* I don't have access to an external loading drive. So I shouldn't put it in? It won't work no matter what? Will it work in my iMac desktop? That doesn't have a tray either.
