Okay, I'm looking for a man page: man -k hotplug finds nothing I'm looking for the file you mentioned: ls /sbin/hotplug ls: cannot access /sbin/hotplug: No such file or directory I'm looking for a package to install related to hotplug: apt-cache search hotplug libxi-dev - X11 Input extension library (development headers) libxi6 - X11 Input extension library libxi6-dbg - X11 Input extension library (debug package) fxload - Firmware download to EZ-USB devices libaws-dev - Ada Web Server development files atmel-firmware - Firmware for Atmel at76c50x wireless networking chips. Seems like there is NOTHING on ubuntu even remotely called hotplug, except /proc/sys/kernel/hotplug which is not a configuration file. What distribution are you using ?
