FadeCandy cannot run.

Hello, I saw that tutorial video you posted online. I like your work very much, and I'm starting to do it now. But I had problems in the first step. Can you help me? I really want to get this lamp.
I just bought a Fade Candy. He can run well on my laptop. But it doesn't work on my raspberry pie.
I inserted FadeCandy into my raspberry pie, and the raspberry pie couldn't recognize it.
I use this command to view the USB device I'm connected to. dmesg | tail -10
The following information appears

Hmmmm. Check your power supply for the Raspberry Pi? They really need to be up to spec. Even a cheap USB power cable can ruin the correct voltage supplied. Remember you are asking the Raspberry Pi to power the FadeCandy board over USB.
