I'd guess that the OS is doing some USB initialization a little strange,
so that the "cold"-plugging code can't work. I've seen similar problems
when OS init scripts don't mount "usbdevfs" before they modprobe
the host controller drivers.
Or there could be something wrong in the boot-time init code, so that
a bit of shell script debugging is in order on your system. Maybe you
can boot in single-user mode and "sh -x /etc/hotplug/usb.rc start" to
watch what it's doing wrong! (Called by "/etc/rc.d/init.d/hotplug start",
as Greg suggested.)
