why usb hotplug not work in 2.5.73

Hi,
I've installed hotplug-2003_5_1, on Redhat7.3, it works fine.
I use a flash memory usb disk, on Rehdat7.3, hotplug will find and insmod the module usb_storage.o when I plug in the disk.
But on kernel2.5.73, it seems hotplug can not insert module usb_storage.o automatically, I must insert the usb_storage.o manually. I also tried to copy "modules.usbmap" from /lib/modules/2.4.18-3 to /lib/modules/2.5.73, same result.
I can see the /sbin/hotplug is already been called and the evironment variable like ACTION is set by kernel correctly. Is there anything more should I do for hotplug?

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.

thanks,

In reply to Ling, Xiaofeng

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.
