Debugging access for goggles with multiple SOC

A goggle includes a plurality of systems on a chip (SoC) sharing a processing workload and a USB port configured to perform low power debugging. The goggles include a USB hub configured to enable a USB port to communicate with a plurality of SoCs simultaneously. The USB hub may be turned off to disable the USB hub, and all SoCs may enter their low power mode without remaining wake up through persistent USB connections. The goggles include switches and control logic to enable the USB ports to perform low power debug or control each of these SoCs. 一种护目镜包括共享处理工作负载的多个片上系统(SoC)以及配置成用于执行低功率调试的USB端口。护目镜包括USB集线器，USB集线器配置成使USB端口可以同时与多个SoC通信。USB集线器可以被关闭以禁用USB集线器，并且所有SoC可以进入它们的低功率模式，而不通过持续的USB连接来保持唤醒。护目镜包括开关和控制逻辑，以使USB端口能够执行低功率调试或控制这些SoC中的每个。
