Abstract: Provided is a USB-compatible apparatus. More particularly, the USB-compatible apparatus integrates a mobile communication module (such as 3G/3.5G/3.75G) and a WLAN module (such as WiFi) into a singular USB apparatus. Inside the body of the USB-compatible apparatus, a routing module is introduced to bridge the mobile communication module and the WLAN module so as to forward the transferred or received data packets therebetween. A plurality of terminal computers can connect to a network via this USB-compatible apparatus since the inside WLAN module provides multiple wireless ports for the terminal computers. The USB-compatible apparatus further has a power-management module for performing arrangement of electric power among the inside modules. The USB-compatible apparatus particularly uses a USB interface to take an external power. Preferably, the apparatus can take power directly from a computer system, or use alternating current or direct current via an adapter.

Abstract: An automatic wireless network linking method with a security configuration includes: providing an access point with a floating service set identifier and a shared key. The floating service set identifier has a prefix name. Next, a host system is provided to execute a setting and linking application to automatically scan the access point with the prefix name and obtain the floating service set identifier of the access point. Both the access point and the setting and linking application perform an operation process to generate a dynamic key. The dynamic key is converted into a wireless network encryption algorithm. Finally, the host system links to the access point to perform wireless communication, and uses the wireless network encryption algorithm to encrypt and decrypt data. Thereby, the time required for setting up the wireless network platform is reduced.

Abstract: A virtual USB port numbers assigning method, applicable to a client device for generating a virtual port representing an actual port of a remote USB hub. The steps comprise: detecting an electrical device connecting to the actual port; requesting data regarding the actual port and the connected electronic device, such as the MAC address and actual port number of the remote USB hub, and the PID and VID of the electrical device; evaluating the data; and assigning virtual ports according to the evaluation result. By assigning fixed virtual port number to each electrical device, so as to prevent the operating system from repeatedly asking users to install the driver program of the electrical device.

Abstract: A wireless remote USB hub apparatus includes a server end operation processor module as the data processing center, for converting and processing data; a server end wireless Wi-Fi communication module is coupled to the server end operation processor module, for transceiving data of Wi-Fi communication protocol format; and at least one USB port, for connecting electronic devices that supports USB, such as a USB drive or printer. When the electronic device connects to the USB port, the server end operation processor module receives a connection signal data from the USB port, converts the connection signal data format into Wi-Fi communication protocol format, and then transmits the connection signal data via the server end wireless Wi-Fi communication module to a personal computer or other client device. Thereby a user of the client device may remotely utilize the electronic device connected to the wireless remote USB hub apparatus.

Abstract: A method of auto-monitoring network ports includes the steps of: receiving at least one path of an application program; detecting whether or not the application program represented by the received path needs at least one network port; notifying a router to open the relative network port required by the application program if the detecting result indicates that the application program needs the network port; and notifying the router to close the relative network port required by the application program if the detecting result indicates that the application program no longer needs the network port. Hence, the present invention can achieve the purpose of exempting users from a mandatory setup of network ports for the router according to different application programs.
