The CY7C66x13 hub part cannot be used because a hub is just a repeater. It does not actually generate the USB traffic sent to the attached devices.
You need a source of data with host capabilities such as generating SOF, USB traffic, suspend/resume... We do have the SL811HS family that has host capabilities. The EZ-811HS Developer's kit is the host with 4 downstream ports. For more info on this product, please go to our web site at www.cypress.com (click on Products --> USB Embedded Host -->SL811HS -->EZ-811HS Developer's Kit).
Alternately, you could use the traffic generation capability of a CATC analyzer to simulate host traffic to your device.
