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.
