Puertos USB no funcionan ubuntu 14.04

He realizado una instalacion nueva, limpia de ubuntu 14.04 en mi lap, HP Probook 6460b, todo bien hasta que conecto una memoria USB, no funciona. He buscado en varios foros pero parece no haber solucion. Llegue hasta aqui confio me puedan ayudar, por favor.

Dejo la salida de dmesg, despues de conectar mi usb.

No soy experto en esto de linux, pero por la salida tengo la impresion de que si las reconoce. Memoria Kingston de 512 MB.

+Tengo que montarla artesanalmente? Vengo de otras versiones de ubuntu y la conectaba y vualaaa todo listo, pero en 14.04 no :-(

Dejo tambien, dos lineas que en de grub, que en otros foros sugerian modificarlas.
