USB TECHNIQUES TO ROUTE POWER TO A USB HOST IN DEAD BATTERY CONDITION

摘要

An example may include routing power between a universal serial bus (USB) host and a USB device. In some instances, power may be routed from the power source of the USB device while the USB host is in a dead battery condition. The various switches of the USB host can be selectively switched to route power from the power source to provide operating power to the USB host''s network.
