An equipment access method configures configuration information of the networked device based on a preset generation strategy. The configuration information includes scenario configuration information of the networked device in at least one application scenario, and the scenario configuration information includes a functional instruction set, and data source configuration information. By preloading the scenario configuration information, device functions of a networked device can be redefined based on the target configuration information, making the device functions more diverse. Based on loaded scenario configuration information, the networked device enumerates descriptors in a descriptor set of the target device based on the functional instruction sets in the descriptor instruction set, configures a target data source when the networked device communicates with the target device if enumeration is successful, therefore effectively avoiding being cracked by malicious programs, ensuring security of the networked device and data.
