I have a Magnetic card reader and two linux machines (ubuntu and fedora) I would like to build an USB driver/data extractor with something like Ruby or Python (preferably ruby) The device plugs and powers on, and sliding a card results in outputing a strange code from wich I would like to extract info like the owner's name and stuff...

More info, lsusb outputs and more are available here:
