PROBLEM TO BE SOLVED: To provide a USB controller and a host computer.MEANS FOR SOLVING THE PROBLEM: A USB controller and a host computer are used for connection to a USB device, and the USB host computer includes: a circuit board having a plurality of first substrate contacts and a plurality of second substrate contacts; a USB connection port installed on the circuit board by the first substrate contacts; and the USB controller electrically connected to the circuit board by the second substrate contacts, and formed with a plurality of pins. Thus, it is possible to reduce disturbance between signals, and to prevent the circuit layout of the circuit board from being too complicated.SELECTED DRAWING: Figure 2 |
