The driver sends first data or instructions to the target equipment; after receiving the first data or the instruction, the target equipment returns second data; and the driver receives second data returned by the target equipment and processes the second data according to the sent instruction. Createfile is a multi-functional function that opens or creates a file or I/O device and returns an accessible handle. The winusb API is a preconfigured API interface. The first data may be a target firmware file, and the instruction is an upgrade instruction (ID _ UPDT instruction). The second data is an upgrade result returned by the target device (the returned ID _ OKAY indicates success, and the ID _ FAIL indicates failure), and the target device may be a USB embedded device compatible with the windows operating system.
S4: and the target equipment receives the target firmware file and the upgrading instruction sent by the user computer and executes equipment firmware upgrading operation.
