Is the power circuit the same as the USB version? (regulator?)

That 100uf on the output of the regulator might make vcc rise a little too 
slowly. Turning on the BOD might help.
But, you don't really need that cap, and it can hurt regulation. 
Try  putting in a 2.2 uf tantalum instead.

Just a possibility...
