Exactly. Evil external USB Hubs, or other USB hardware that has access to a USB bus. You already know I'm paranoid, but consider when technology allows it *someone* is gonna make something of the sorts, and it's responsiblity of the industry to protect everyone from that. I'm not wrong in this, or am I confusing a wicked world with a wonderland that treats everyone fairly regardless of their political, social, race, sex or religious status? <snip regarding macally keyboard> > It should be possible, but it's not necessarily easy.

I'm looking for experiences here. If I rewire my keyboard that's my business (I did buy it after all, it is not partially owned by any government, corporation, or other entity, not even god, it's mine and I shall do with it as I wish) and I suspect rewriting the keyboard mapping in the kernel isn't all that hard. regards, -peter -- Here my ticker tape .signature #### My name is Peter Philipp #### lynx -dump "http://en.wikipedia.org/w/index.php?title=Pufferfish&oldid=20768394"; | sed -n 131,136p #### So long and thanks for all the fish!!!
