    Thanks, MarkT. This is my first board of this complexity and I'm still learning while doing it. The weird thing is that it all works absolutely fine while powered from USB. No audio noise, no hot spots on the board...

    A sad update. I've found Adafruit's diagram for the 1000C board and decided to "reflow" it onto my board. Got all of the specified parts, all in proper footprints, and made a new board with the charger on it....

    Thanks guys. Just got the 1000C at DigiKey. Looks twice as complex as what I had, but I hope it works. Will let you know. This is so strange. This is the third time I'm posting a reply and they just keep...

    Turns out that it's my battery charger. When I use power from the PC USB, the USB host works fine. As soon as I enable the battery charger, the USB host never puts out the 5V. I'm sure the charger limits the current...
