Looks like you init routine for the kernel module is failing with this error.
Can you provide the kernel  module which you are using.
It will help us understand the problem more precisely.

It means that the resource you are trying to use/access some resource
which is busy. In that the error -EBUSY is returned, which eventually
means the same.


Just as an example,

mount a <dev> to <mountpoint>
cd <mountpoint>

try to do a umount <mountpoint>

You will see a device or resource busy error. And try to co-relate it
with what I mentioned.
