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 packet processing method comprises: receiving data packet including a key message; analyzing the key message; determining whether the data packet is a high priority data packet or a normal data packet according to a result of analyzing the first key message of the data packet; and executing an Rx high priority interrupt in response to determining that the data packet is the high priority data packet. The Rx high priority interrupt is to immediately transmit an interrupt signal to interrupt receiving of the data packets.

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.
