Detect if a digistump is connected to USB

[7eggert]

I'd like to do someting like this:

if (connected_to_usb_host()) {
 while (1) delay (1000); // be nice to PCs
}

wreck_havock_on_the_usb_pins(); // I need all of those pins

I googled, I searched the forums. I'm surprised to not instantly find a solution in the FAQ, even if it would be "you can't".

Did you managed to find a solution for this?
