A universal serial bus (USB) device communicates with a USB host over a USB to remotely wake up the USB host over the USB when the USB host is in a low power (e.g. deep sleep) mode. The USB device performs an activity to wake up the USB host. The USB host performs a remote wake up process in response to detecting the activity by the USB device. The USB host performs a resume process in response to performing the remote wake up process by the USB host. The USB device wakes up in response to the USB host performing the resume process.
