¡Buenas tardes!

Hace tiempo instalé ubuntu 9.04, lo dejé tal y como lo queria ... Al cabo de un tiempo 3 meses todos los dispositivos usb pasaron de ser USB 2.0 a USB 1.1. como no conseguia hacerlos funcionar a 2.0 he vuelto a instalar Ubuntu 9.0 pero esta vez no hay manera que mis USB vuelvan a funcionar como 2.0.

Necesito vuestra ayuda

El dmesg me da este error en los usb ... muchas grácias

Ya he solucionado el tema, no ha sido de mi total satisfacción, creo que el problema viene por la nueva actualización de Ubuntu 9.04, ya que he instalado la 8.10 y no he tenido ningún problema, todo ha funcionado a la perfección.
