 Ok. After playing with my BIOS settings, i decided to reset them all.
 And here, i can say that i previously made a mistake: *disable* ACPI at
 boot time _do_ the trick!
 
 So, i ended with these two systems:
   - notebook: FreeBSD 5.2.1 + ACPI enable  => USB ok
   - notebook: FreeBSD 5.3   + ACPI disable => USB ok
 
   - desktop:  FreeBSD 5.2.1 + 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.

 PS: Sorry Anish for the mistake in the first place.
