hahahaha I wish I could... well, you are _always_ welcome to donate me
yours ! =P
I'll try more later to get one of those readers...

Reading Greg's comment, now I'm in doubt if this should really be in
kernel mode or at userspace. Since there is no standard (AFAIK) for
those readers, how should it be done ?

Another thing: where can I find documentation about the USB
architecture ? For example, I suppose that some (or all) USB devices
may have DMA capabilities... how is this done ?
