Hi,

I have used the functions copy_to_user and copy_from_user in the driver to
get and send data to user space. If  I comment the above statements,  i dont
get the errors when i insmod usb-skeleton.o which i get when i use the
copy_to_user and copy _from_user functions.
errors --->

Using usb-skeleton.o
insmod: Relocation overflow of type 4 for __copy_user
insmod: Relocation overflow of type 4 for __copy_user
insmod: Relocation overflow of type 4 for __copy_user
