Embodiment Construction
[0046] The present invention provides an information processing method and an electronic device. First, the electronic device includes a first connection interface (such as a USB interface), and the method includes: disabling the first chip processing of the first function corresponding to the first connection interface state (that is, when the USB interface is in a disabled state, the USB interface will not be able to realize data transmission with the electronic device), detect whether a second electronic device is connected to the first connection interface, and then detect the second electronic device Whether it is an electronic device corresponding to the second function (such as: an electronic device for inputting data such as a keyboard, a mouse, etc.), when the second electronic device is an electronic device corresponding to the second function, control the first connection interface to receive data from the second electronic device the data signal, so that the first e...

The invention provides an information processing method and an electronic device. The electronic device comprises a first interface. The method includes detecting whether a second electronic device is connected onto the first interface when a first chip with a first function and corresponding to the first interface is in the energy forbidden state, then detecting whether the second electronic device is the electronic device that a second function corresponds to, and controlling the first interface to receive data signals from the second electronic device on yes judgment to enable the first electronic device to receive and process data signals generated by the second electronic device. Therefore, the technical problem in the prior art that devices such as a keyboard and a mouse cannot be connected with the electronic device due to the fact that the input devices such as the keyboard and the mouse are forbidden when a universal serial bus (USB) interface in the electronic device is in the forbidden state is solved.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] With the continuous development of electronic technology, the performance of electronic equipment is constantly improving. For example, a computer is initially equipped with a PS / 2 interface, which can be connected to a keyboard or mouse corresponding to a PS / 2 interface, so that users Other electronic devices can be connected to the computer through this interface. [0003] Due to the limitations of the PS / 2 interface, the USB interface is used in computers or other electronic devices in the prior art. Since the USB interface is an open interface, it is possible to connect a USB flash drive or a mobile hard disk to the computer through the USB interface. , USB keyboard, USB mouse and other external electronic devices, but, in order to ensure the security of data content in the computer,...
