Abstract: PROBLEM TO BE SOLVED: To provide an improved technique for removing a smart card from a mute mode. SOLUTION: 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.

Abstract: A USB device, integrated circuit, smart card and method are disclosed. A USB transceiver is connected to a data interface and operable at a respective low speed and full speed configuration. A processor as a USB device controller is operatively connected to the low speed USB transceiver and full speed USB transceiver and operable for transmitting a different device descriptor to a USB host for performing an enumeration depending on whether a low speed or high speed operation is chosen.

Abstract: An integrated circuit for a smart card may include a universal serial bus (USB) transceiver for communicating with a USB host device, and a microprocessor connected to the USB transceiver and operable in a test mode and a user mode. When in the test mode, the microprocessor may perform a test operation based upon receiving at least one test vendor specific request (VSR) from the USB host device via the at least one USB transceiver. By way of example, the test operation may include scan testing the microprocessor's control logic, detecting a status of at least one buffer and communicating the status to the USB host device, writing test data to at least one designated buffer and sending the test data from the at least one designated buffer to the USB host device, and/or operating with reduced power.
