La distribucion que tengo es linux mint 5, pero tambien me pasaba con ubuntu 7.10. en cuanto pueda posteo la informacion que me de el mseg en el momento del bloqueo del raton y teclado y a ver por donde viene el problema.
Justo depues de que me fallara he hecho un dmesg, copio y pego a partir del primes error hasta cuando vuelco a conectar de nuevo el raton.
