your question is really vague, but is sounds like you are asking for a bit 
of code to open a scanner device file so you can send your own packets to 
it?

i would not use the kernel usb scanner module (rmmod scanner) i would 
instead use libusb and the usbdevfs instead. see the attached bit of code. 
you will have to change the vendor and device ids.
