    So I am building a NES RetroPi. Old busted NES case that I am putting a Pi 2 with retropie 3 in it.

    For the most part i followed https://www.youtube.com/watch?v=R2Peo5wX1NU this video.

    I am using:
    Raspberry Pi 2
    Belkin AC Powered Ultra-Slim Series 4-Port USB 2.0 Hub (F4U040v)
    Mausberry USB shutdown switch
    5V 2.6A output AC adapter to power the hub

    When I power the Pi with my 2A micro usb adpater everything is fine

    When i Power the Pi going through the USB Hub I get a strange rainbow icon in the top right corner of my display that never goes away.

    1. What is that icon for?

    2. I am triyng to do the setup scrtip for my shutdown circuit but i am not sure which one to use: http://mausberry-circuits.myshopify.com/pages/setup
    The one for RaspBMC/Raspbian/Debian distributions or the one for Arch distributions

    Any help would be awesome.

    1) the icon means there is not enough power being supplied, so it looks like your hub doesn’t output enough power for the pi. strangely, that hub model appears in the ‘working’ list of RPI hubs (http://elinux.org/RPi_Powered_USB_Hubs#Working_USB_Hubs) with a comment that it powers the pi fine, but perhaps they’ve not tested with the pi2, or using applications that push the system as much as emulation.

    not sure about 2!
