An integrated circuit for a smart card may include a universal serial bus (USB) transceiver and a microprocessor connected to the USB transceiver and operable in a test mode and a user mode. The microprocessor, when in the test mode, upon receiving at least one test request from the USB host device may cause the USB transceiver to output test data, read back the test data from the USB transceiver, compare the test data with the test data read back from USB transceiver, and generate test results for the USB host device based upon the comparison.
