A dynamic data transmission format adjustment method is provided. Firstly, a peripheral device raw input data is acquired from a device main body of a wireless peripheral device. Then, the peripheral device raw input data is converted into a variable-bit-length peripheral device transmission data according to a dynamic data transmission format conversion rule. Then, a network transmission packet containing the variable-bit-length peripheral device transmission data is generated, and the network transmission packet is transmitted to a wireless receiver of the wireless peripheral device. Then, the variable-bit-length peripheral device transmission data in the network transmission packet is converted and restored into a fixed-bit-length peripheral device transmission data according to the dynamic data transmission format conversion rule. Then, the fixed-bit-length peripheral device transmission data is transmitted from the wireless receiver to a computer host.

A wireless input system includes a first computer, a second computer, a first-mode wireless connection device, a first input device and a second input device. When the first-mode wireless connection between the first input device and the first-mode wireless connection device is established and the first-mode wireless connection between the second input device and the first-mode wireless connection device is established, the first input device and the second input device can be operated to control the first computer. When the second-mode wireless connection between the first input device and the second computer is established, the second input device can follow the first input device to perform a connection switching operation. Consequently, the second-mode wireless connection between the second input device and the second computer is established.

A power saving method for a peripheral device in a wireless operation mode is provided. The power saving method at least includes the steps of allowing the peripheral device to enter an idle mode and judging whether the peripheral device receives a startup trigger event. In the idle mode, the light source in an operation region of the peripheral device is in an on state or a high-brightness state. If the peripheral device receives the startup trigger event, the peripheral device is switched from the idle mode to a power saving mode. In the power saving mode, the light source in the operation region of the peripheral device is in an off state or a low-brightness state. The peripheral device in the power saving mode consumes less electric power than the peripheral device in the idle mode.

Power saving method for peripheral device

A USB device and a firmware updating method for the USB device are provided. The firmware updating method includes the following steps. Firstly, a communication protocol is provided. Then, the communication protocol is installed in the at least one microcontroller unit of the USB device. Then, an application program is produced according to the communication protocol. The application program is installed in an electronic computer. The application program contains at least one update firmware information. Then, the at least one update firmware information is transmitted from the electronic computer to the at least one microcontroller unit through the communication protocol. Consequently, at least one original firmware information in the at least one microcontroller unit is replaced by the at least one update firmware information.

USB device and firmware updating method thereof

A wireless mouse includes a mouse body and a wireless receiver. The wireless receiver is connected with a computer host. When the mouse body is operated by a user, an original information is generated. The original information is encrypted and converted into an encryption information by the mouse body. The wireless receiver receives the encryption information from the mouse body. After the encryption information is received by the wireless receiver, the encryption information is decrypted by the wireless receiver. Consequently, the encryption information is restored into the original information. After the computer host receives the original information through the wireless receiver, the computer host performs a corresponding operation.
