Hi, I've already solved the problem. I simply made an update and upgrade to my BBB ant it solved the problem. Now i can plug and unplug my devices and they are recognized by the BBB.
I discovered that some releases of Angstrom has that problem, I've tried a few and some have and others don't, now i'm using the release from September 2013 and it's working. Thanks for the tips and for the replies.
