  • CONTROLLER AND TRANSFER SPEED CONTROL METHOD
    Publication number: 20150261712
    Abstract: A USB 3 host controller according to the present invention includes a transfer speed switching unit besides a transfer data converting unit that mutually converts transfer data from a USB device and transfer data from a PCI Express bus. The transfer speed switching unit receives transfer information regarding data transfer from the USB device via a USB 3 interface when the USB device is connected, and identifies a transfer speed used by a PC side according to the transfer information or a result of analyzing the transfer information. Then, when a current transfer speed of the PC side is different from the identified transfer speed, the transfer speed switching unit transmits a speed switching signal indicating switch to the identified transfer speed to a PCI master via a PCI express interface.
