  In case of NG
Supplement:
It is impossible to determine is the [USB TO DEVICE] 
terminal or [USB TO HOST] terminal is defective in case of 
NG.
The USB Storage Check can be used to check the [TO 
DEVICE] terminal. Combine the test to determine which 
terminal is defective.
Be sure to use a USB Storage whose operation is already 
checked. It does not matter if it is equipped with a disk or not.
