As shown in FIG. 1, the method for detecting an electronic device includes steps S110 to S140.

In step S110, it is detected whether the electronic device receives an insertion event of a collection device.

In step S120, if yes, determine whether the attribute information of the collection device matches the configuration information stored by the electronic device.

In step S130, if there is a match, the state of the acquisition device is set to an available state.

In step S140, if there is no match, the state of the collection device is set to an unavailable state.

After the electronic device is started, the method can determine the state of the collecting device by detecting whether the electronic device receives an insertion event of the collecting device. Specifically, if it is determined that the electronic device receives the insertion event of the collection device, it can be further judged whether the attribute information of the collection device matches the configuration information stored by the electronic device, and if it matches, the status of the collection device is set to an available state, otherwise, If they do not match, the status of the collection device is set to an unavailable state, so that the user can know the status of the collection device in real time, which will not affect the user's use and improve the user experience.
