      Hi Folks,

      I have a AP5754K board and for quite a long time now the board is “ping ponging” with USB disconnect/connect and board blanking and reappearing multiple times throughout the day.

      I’ve changed the cables , PC nothing seems to work.

      A new issues with this same board is – When you try and turn it on in the morning , the light flashes red/green for 10 seconds, then stays red and the board doesn’t come on.

      Yesterday I disconnected everything and powered the board down , then powered just the board up and it came back on. This morning that didn’t work and I finally got it on when I disconnected the Active Connect.

      Any help would be grateful.
