<p>A universal serial bus (USB) smart card can be automatically reset from a mute mode. A processor on the smart card writes its status to a status register. A USB device controller polls the status register to determine the status of the processor. If the status from the status register indicates that the processor has entered the mute mode, the USB device controller initiates generation of a reset signal to reset the processor out of the mute mode.
