Just a side note, the desktop on which the problem (still) occurs follow
the RELENG_5 branch and the build used at this time is as follow:
  FreeBSD 5.3-STABLE #0: Fri Feb  4 05:38:57 CET 2005

But since mid/end-december 2004 (for ~2 months now _approximatively_) i
encountered systematically an interrupt storm from the USB host controller
which prevent me inevitably to be able to use all of ly USB devices:
  Interrupt storm detected on "irq10: uhci0 uhci1+"; throttling interrupt
source

In this context, if i reenable ACPI support on boot, i didn't see any
interrupt storm problem anymore... but i still can't use USB on this
system.

So, i now had an unusable USB system:
  - ACPI disable / uhci interrupt storm (doesn't even get the device
    created on the fly) => unusable USB devices
  - ACPI enable / "conflict" with USB stack (doesn't even get the device
    created on the fly) => unusable USB devices

Any advice?
