RE: why usb hotplug not work in 2.5.73

["Ling, Xiaofeng" <xiaofeng.ling@intel.com>]

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.
