So, how did it go? Are you about to put what you've gleaned into a web page? What I would like to know should be simple. What can be hotplugged into a running X-window session and what can't? I can plug in my mp3 player, as long as it's off, then turn it on and Fedora sees it as a storage device. Nice! I plug my cellphone in, X locks up hard. So, what's the Real Deal on just plugging something in, as a general rule?? I'm hoping there is a general rule! <grins> Ric -- ================================================ My father, Victor Moore (Vic) used to say: "There are two Great Sins in the world... ..the Sin of Ignorance, and the Sin of Stupidity.
