I have created a new initrd file with a new name and added a new entry in the /boot/grub/menu.lst file. Then, I booted from this newly added entry and got the debug messages.

I guess this is not possible as usbhid is depends on the usbcore module. If we unload the usbhid module then we can not unload and load the usbcore module as the keyboard and mouse will not work at all. I tried this yesterday, but I did not unload and load the usbcore module as either keyboard or mouse was not worked at all. Is there any way to getridof this issue? Anyway, thaks for your help and suggestions, always.
