 I correct myself one more time:
   - notebook:  FreeBSD 5.2.1 + ACPI enable  => USB ok
   - notebook:  FreeBSD 5.3   + ACPI enable  => USB ok
   - notebook:  FreeBSD 5.3   + ACPI disable => USB ok
 
   - desktop:   FreeBSD 5.2.1 + ACPI enable  => USB ok
   - desktop:   FreeBSD 5.3   + ACPI enable  => USB ko :(
   - desktop:   FreeBSD 5.3   + ACPI disable => USB ok
