Abstract: A computer system is provided comprising a non-volatile storage medium and a processor. The processor acquires authentication information from a first removable storage device, stores the authentication information into the non-volatile storage medium, and forbids data access of the computer system when detecting that a second removable storage device has been inserted and identification data of the second removable storage device is different from the authentication information.

Abstract: A method for controlling icon display corresponding to a Universal Serial Bus (USB) Mass Storage is provided. The USB Mass Storage is electrically connected to a USB port of a personal computer. The method includes: when it is detected that there is nothing inserted into any memory card slot of the USB Mass Storage, preventing the USB Mass Storage from triggering a specific icon to be displayed, wherein the specific icon is selectively utilized for indicating that at least one USB device is electrically connected to the personal computer; and when it is detected that a memory card is inserted into any of at least one memory card slot of the USB Mass Storage, allowing the specific icon to be displayed. An associated personal computer and a storage medium storing an associated USB Mass Storage driver for controlling icon display corresponding to the USB Mass Storage are further provided.

Abstract: A method for controlling power consumption of a Universal Serial Bus (USB) Mass Storage is provided. The USB Mass Storage is electrically connected to a USB port. The method includes: monitoring at least one Test Unit Ready (TUR) command from an operating system (OS) to the USB Mass Storage; and when it is detected that there is no other command from the OS to the USB Mass Storage for a predetermined time period, controlling the USB port to enter a suspend mode in order to save power supplied to the USB Mass Storage. An associated personal computer and a storage medium storing an associated USB Mass Storage driver for controlling power consumption of the USB Mass Storage are further provided, where the personal computer includes the storage medium. In particular, when the USB Mass Storage driver is executed by the personal computer, the personal computer operates according to the method.

Abstract: A method for enhancing performance of data access between a personal computer and a USB Mass Storage is provided. The personal computer is equipped with a plurality of layers of drivers regarding USB data access, and a lower layer of the layers of the drivers includes a USB Bus Driver. The method includes: monitoring commands sent from an operating system (OS) file system to an upper layer; and when a command sent from the OS file system to the upper layer is utilized for accessing data of a data amount that is greater than a predetermined threshold value, omitting a portion of a plurality of IRPs, automatically generating a plurality of replies for replying to the omitted IRPs, and altering at least one IRP of remaining IRPs in order to correctly access the data with a lower IRP count, wherein the plurality of IRPs is associated with the command.

Abstract: A system, a testing apparatus, and a method for testing at least one device with a connection interface are provided. The system comprises a host, a testing apparatus, and a power supply. The testing apparatus further comprises a microprocessor and at least one current limit module. The host sending a test signal. The power supply provides a voltage to the testing apparatus. The at least one current limit module of the testing apparatus, which is electrically connected to the microprocessor, the at least one device, and the power supply, provides the voltage to the at least one device. When the current passing through the at least one device is greater than the predetermined value, the at least one current limit module of the testing apparatus stops providing the voltage to the at least one device and sends an over current signal to the host via the microprocessor.
