I am trying to use a WP7504 with the Red mangOH board. When I power up the board, the USB ports load on the PC, but after about 5 seconds they disconnect and reconnect after about 5 more seconds. This cycle continues until I remove power. I am seeing all this in Device Manager.
The chip has the latest firmware, as I just loaded it using a Green mangOH board. It works fine with the Green board and the same PC.
I have tried a WP8548 on both the Red and Green boards and it works fine. Is there something different with the Red board that would make the chip continually reset?
Any suggestion or help would be appreciated.
