Help with a Dell external DVD ROM

i have a dell external dvd rom which was given to me by a friend but the only thing is want to use it on an hp laptop. The usb port on the dell looks like a double usb port and was made to plug into 2 ports at the same time on the dell laptop but it cannot be plugged into my hp. Does anyone know if there is a part i can purchase to place on the on the dell’s double usb cord so i can use it on my hp computer?

Thanks!
