What subsystem replaces /sbin/hotplug in CentOS 5? The older hotplug package is missing from CentOS 5 and /proc/sys/kernel/hotplug yields an empty string. Since hotpluging for standard devices still seems to work, I presume that something replaces the hotplug helper found on CentOS 4. Can someone point me in the right place? All of my Googleing points me back to the (obsolete?) /sbin/hotplug subsystem (Google is just not being helpful!). I'm guessing udev and/or HAL are involved somehow, but I am having a hard time figuring out what I need to do.
Specificly, I have a special USB device (a PI Engineering Rail Driver Console device) that I have written a daemon for that I need to launch when the device is plugged in and when the device is unplugged, the daemon needs to be killed. For CentOS 4, I used a script fired up from the /sbin/hotplug via /etc/hotplug/usb.usermap -- what to I use for CentOS 5 (and eventually CentOS 6)?

I think you are supposed to use udev and /etc/udev/rules.d/
Geting up HP Printer on CentOS 5.x when USB 2.0 does not work properly:
modprobe -r uhci_hcd; modprobe -r ehci_hcd; modprobe uhci_hcd; modprobe ehci_hcd
usb_printerid /dev/usb/lp0 udevd restart service haldaemon restart
If firmware loading during intallation does not work, use:
make install-hotplug !!! (in /etc/udev/rules.d add 11-hplj10xx.rules file ???)
