I am seeing a USB-PWR drop ind interrupt.  What does this mean?  Why can it occur?

I cant find documentation.

    What device part number are you using?

    Is there a software release you are using that may be using this USB-PWR as a reference?

    If you can provide more detailed information on the collateral you are leveraging, this might help the investigation.

    For MSP430 devices with USB capability, the Family User's Guide has a section on the USB module which includes the integrated LDO for powering the device from the USB 5V supply, if appropriate.  Perhaps this is in reference to that subsystem.
