What should a self-powered node do after peripheral power cycling?

If the peripheral is powered back up, the microcontroller (MCU) must apply either a hardware or a software reset to the USBN9603/4, forcing the node to go to its default (i.e., not attached) mode. When the host detects that the peripheral is unattached, it re-initializes the peripheral and attaches the node. The host detects the re-initialization and initiates the enumeration process. This mechanism is already implemented in the sample code.
