How to test USB devices without using a PC ?


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 (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.
