Abstract: An error handling method for a transmission interface connecting between a first device and a second device for performing data transmission between the first device and the second device, wherein a connection type between the transmission interface and the first device is a direct interface (DI) and the connection type between the transmission interface and the second device is an indirect interface (II), and the error handling method comprises: when an error is detected at the direct interface, reporting an error event to a host of the first device; when an error is detected at the indirect interface, attempting to handle the error without letting the host discover it; and when the error detected at the indirect interface is determined as unable to be solved, reporting another error event to the host.

Abstract: A USB interface system capable of automatically adjusting connection speed and power consumption capability and a method thereof are provided. The method includes configuring a slave device to perform a first handshake procedure with a main device, and communicate with the main device by using a first connection specification; detecting a first power-off event by using a slave power detection module; when the first power-off event occurs, recording first power-off information by the memory unit. If the slave device is re-connected to the main device, the slave power detection module is configured to perform a second handshake process with the main device, and determine to re-communicate with the main device in a second connection specification different from the first connection specification according to the first power-off information.

Abstract: A data-transmission-format conversion circuit has a first data transmission interface, a second data transmission interface, and a control circuit. The control circuit is coupled to the first data transmission interface and the second data transmission interface for processing data-format conversions between the first data transmission interface and the second data transmission interface. The control circuit is further used to control the second data transmission interface to switch from a first corresponding power mode to a second corresponding power mode when the first data transmission interface is switched from a first power mode to a second power mode. The control circuit is further used to control the second data transmission interface to switch from the first corresponding power mode to a third corresponding power mode when the first data transmission interface is switched from the first power mode to a third power mode.
