    Abstract: A method of installing a driver for a plug and play device is provided, wherein the plug and play device includes a main function device and a storage device meeting a standard specification. The storage device stores a driver required by the main function device. The main function device and storage device may be connected to the host in two different ways after the plug and play device is installed to the host. The first way is to connect the two devices to the host simultaneously. The host loads a built-in standard driver for the storage device from the host to access the storage device, and then loads the driver required by the main function device from the storage device to gain freely access to the main function device. The second way is to connect the storage device to the host, and to cause the host to copy the main function device driver from the storage device to the host's storage device (e.g., a disk drive). Next, the main function device is connected to the host. At this time, the host can directly load the copied driver for the main function device and retrieve the device accordingly.

    Abstract: A method for driving a brushless DC motor is disclosed in accordance with the present invention. Firstly, a driving control signal is generated based on sensed information of a motor rotor's magnetic field distribution. The driving control signal is inactive in the case that four rotor magnetic arcs are rotated more or less than critical positions of the rotor corresponding a stator. At that time, no magnetic fields are produced from the motor's stator, and thus the rotor rotates by inertial force. In another case, the driving control signal is issued in a conventional manner.
