Hello All,
I am trying to figure out how the linux kernel passes information about
USB devices to other programs. I have written a program that needs to
realize if I have plugged in a new USB device. My program can already
see/read/write to a device if it's plugged in before I start the
program. But, I need to be able to keep this program running always
and if I plug in a new USB device, my program needs to realize that it's
there. Is this possible in Linux?
If I plug in a USB device, a message shows up in one of my terminals
saying that a device has been plugged in. Is there a system wide
message that is being sent that I can catch with my already running
program? Or, since /sbin/hotplug gets called automatically when a USB
devices is plugged in, is the easiest way just to modify this script to
open a socket to my program and to notify it that way?
Thanks for your input,
Danny
