Not hotplugging mouse in Xorg

[Loïc Grenié]

      Hi,

      my USB mouse and keyboard disconnect and reconnect often (hardware
  problem) and I need that the "main" X server does *not* use them
(anti-hotplugging).
  Does anyone know how to do that with Lucid ? With Karmic it was possible
  fiddling with hald but I've not found how to do it with Lucid.

     Thanks,

         Loïc
