 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
 
 >  The desktop is the machine equipped with the MSI K7T266 Pro2 motherboard.
 >  Note: the BIOS firmware is up to date with the last revision available.
 >
 >  The update during the RELENG_5 branch seems to be at the origin of the
 >  USB support problem on this motherboard.
