To provide an improved technique for removing a smart card from a mute mode.

A universal serial bus (USB) smart card can be automatically reset from a mute mode. A processor on the smart card writes its status into a status register. A USB device controller polls the status register to determine the status of the processor. When the status from the status register shows that the processor enters into the mute mode, the USB device controller starts generation of a reset signal for resetting the processor from the mute mode.
