USB hotplug

Hi all,
is there a way to have the usb hotplug on my BeagleBone Black? My angstrom version is: Linux beaglebone 3.8.13 #1 SMP Thu Sep 5 20:26:50 CEST 2013 armv7l GNU/Linux. On google I did not find anything, but for my project I do I need to remove and replace USB devices.

Some help?

Thanks to all

Giuseppe
