1.
Connect
a
USB
MSC

though
a
USB
cable;
1.1
If
your
USB
MSC
storage
device
is
2.5”
USB
hard
disk
and
without
additional
power
supply
unit,
you
may
connect
an
additional
5V
DC
power
supply
to
JP10
of
DX
evaluation
board
then
turn
on
SW2.
It
can
help
resolve
possible
insufficient
power
problem
of
the
2.5”
USB
hard
disk.
Note
that
5V
DC
power
supply
unit
addresses
usually
seen
insufficient
power
issue
with
using
a
2.5”
USB
hard
drive.
It
is
not
required
with
other
USB
thumb
drives.
