A method for providing a solution to ADB port occupancy includes: adding functional compound information to attribute information of an ADB device; setting descriptor information of the ADB device as preset descriptor information if VID and PID of the ADB device are consistent with preset VID and preset PID; the preset VID, the preset PID and a corresponding interface number are added to an ADB driver information file of a PC device; modifying a communication port number into a preset port number in an ADB communication program; installing a corresponding ADB driver if it is determined by the PC device that the VID, PID and interface number of the ADB device are consistent with the preset VID, the preset PID and the preset interface and that the descriptor information of the ADB device is the preset descriptor information; and setting the communication port number as the preset port number.
