Can you enable the debug messages for hotplug to see what it spits out
when you plug in your device?
And don't copy modules.usbmap from one kernel to another, they are tied
to that specific kernel version.

Ok, I have found the reason from the DEBUG message.
I have installed the new kernel 2.5 modutiles, by default, it is installed in /usr/local/sbin.
The old one for kernel 2.4 is at /sbin/, at command line, when I type "modprobe", the new one will be found first,
but in hotplug scripts, the old one will be found first. So the usb-storage module can not be inserted.
Thanks a lot.
