For DPA tool(it is very good for customers) works, I think first I want to make this part code working, then you can decide if you pickup or not. Old ioctls work with DPA tool. From your comments, looks old implementation does not work. Need I use "register_ioctl32_convension" and "unregister_ioctl32_convension"? Thank you so much! wendy
