It looks like it's rebooting whenever the channel scan starts. Possibly the power supply failing. Do you have another 5 volt power supply you can use to test with? It needs the following specs:

5V 1A regulated power adapter (higher A rating ok)
2.1mm ID / 5.5mm OD plug, 9-10mm depth, center positive
