Cannot get Janome 10001 to read via USB direct... My Janome 10001 states that you can use USB

Question

My Janome 10001 states that you can use USB cables to directly transfer a .jef embroidery file from computer to the sewing machine.  I have tried everything--new cables, attempting to find drivers, etc. but just cannot make it transfer.  No where does it say that you have to have any additional software to do this--such as the Janome customizing software.  Does anyone know how to do the transfer by cables?  Thanks, Nina
