If you are using udev, and have configured the kernel for hotplug
support, this should not be necessary. The kernel will generate the
appropriate hotplug events, and udev will create the device nodes.

Write udev rules to create persistent device names.
An example:
BUS=="usb", KERNEL=="sd[a-z]2", SYSFS{serial}=="300000005AF6",
SYMLINK="%k", NAME="backups%e"
