1. A system to minimize power leakage, comprising:
a system-on-chip (SOC), wherein the SOC includes a Universal Serial Bus (USB) physical subsystem, wherein the USB physical subsystem is to receive USB related events; a power management logic including USB wake functionality and USB On-the-Go (OTG) functionality; and a power management apparatus comprising local registers to the power management apparatus to record the VBUS and ID pin value changes, wherein the local registers trigger virtual interruptions, wherein the virtual interruptions include sensing the attachment or detachment of a USB cable.
