module can't get version number of the corresponding device

[Hong Hsu <honghsu@bellatlantic.net>]

When I install a module, the /var/log/messages reports error on can't 
get version number of the corresponding device.   I am new to this.  Can 
someone point out what is wrong.  Does this has something to do with 
devfs as I notice if a USB device was plugged in after the system's 
boot, #insmod always gives this error.

Following is log file.  Your help will be appreciated,
