Roland UM-ONE mk2 Roland MIDI Interface - Almost Unused

【Roland UM-ONE mk2】
After purchasing, I connected it once to test it, but I couldn't figure out how to use it afterwards and kept it stored at home.
I no longer have the equipment to connect it to, but I was able to confirm that it powers on by connecting it to a MIDI keyboard and computer (see 5th photo).

The outer plastic case has scratches, but since the main unit was not taken out for use, there is no damage to the unit itself.
All accessories are included.
This item has been stored at home for a long time, so please check the photos and purchase with the understanding that it is a used item.
