When Portable disk is connect with the automatic heating swappable device 20, which inquires the parameter of the universal serial bus Portable disk,
And after the corresponding device node of generation and accumulative operating result, the connection with the universal serial bus Portable disk is disconnected, with
Reach the yield that the universal serial bus Portable disk is judged via the mode of automation.It further says, which passes through
Four of the relay control module 21 signal line connections and the general string are detected by the Universal Serial Bus Interface 11
Four of row bus Portable disk data line connections, i.e., the equipment for the universal serial bus Portable disk being inquired by the main control module 10
The parameters such as descriptor, configures descriptor, interface descriptor, and the lower corresponding driver of loading is being met the requirements, it should with generation
Device nodes, and the main control module 10 is opened the device nodes after the device nodes are detected, is configured, is closed
Operation, and after recording result, wherein operate it is all successful then add up to add 1 for success value, it is on the contrary then the value that writes off adds 1, Ran Houyou
The main control module 10 sends a command to the processing controller mould of the automatic heating swappable device 20 by the network connectivity device 12
Block 22, then the relay control module 21 is driven to disconnect via universal input and output (GPIO) by the processing controller module 22
Four signal lines, so as to which the universal serial bus Portable disk be made to disconnect the connection with the relay control module 21.Finally
When counting yield, which will be equal to the number of universal serial bus Portable disk test plus the quantity of the fail values
Afterwards, it just stops operation, and counts the yield of the universal serial bus Portable disk and output result.Those skilled in the art should
Understand, as long as employing technical solution the same or similar with the present invention and having reached and the same or similar technology of the present invention
Effect, all belong to the scope of protection of the present invention within, specific embodiment of the invention is not limited.
