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 ?

I also hope that it is the same... Also the laptop integrated one is USB device.

Oh... I really don't know... You can buy a new laptop :) Best Regards, Alon Bar-Lev.
