Summary:The utility model provides a detection device for detecting whether the functions of a chip are normal or not. The detection device comprises a switch which is positioned between a chip to be detectedand two USB connectors and is arranged in a GPIO manner; the GPIO switch connects the two pins of the chip to be tested with the two USB connectors through data lines. Wherein two pins of the chip tobe tested are respectively a USB-D + differential line and a USB-D differential line; the two USB connectors are respectively a first USB connector connected with a PC and a second USB connector connected with a USB flash disk; the two USB connectors are respectively provided with two data lines led out from two pins and can be connected with a first position or a second position in the GPIO switch, and one of the two USB connectors is decided to be connected by controlling the GPIO switch; when the switch is switched to the first position, the chip to be tested is connected with the first USB connector through the da
