A universal serial bus (USB) connector for connecting a host and a universal serial bus device includes a main body, a first pin disposed in the main body connecting to a power supply, a second pin disposed in the main body transmitting signal D-, a third pin disposed in the main body transmitting signal D+, and a fourth pin disposed in the main body connecting to ground. The third pin is shorter than the second pin by a predetermined length, whereby the host recognizes the universal serial bus device correctly when the universal serial bus device is connected to the host by the universal serial bus connector from the host.
