A management method for a USB includes the step of detecting number of electronic devices connected to USB interfaces in a first group, and the USB interfaces in the first group are coupled to a first control terminal. Number of electronic devices connected to USB interfaces in a second group is detected, and the USB interfaces in the second group are coupled to a second control terminal. A third group is provided, and USB interfaces therein are switched to be coupled to the first or second control terminal. Number of electronic devices connected to the USB interfaces in the third group is further detected in the invention. The USB interfaces in the third group are determined to be coupled to the first or second control terminal according the numbers of the electronic devices connected to the first, second, and third groups. The working performance of the USB is improved.
