Hi
I have a big problem with CYUSB3304 super speed signal on my board. I checked all impedences with a software PCB design and the that's all right, but it's working only usb 2.0 and create a simple " generic hub " on Windows 7. The revision chip is " E" without external Eeprom, and all settings into internal ROM are corrects, and i tried to change the physical chip but doesn't work again.
Have you any information or other cases about this problem?
Is it possible some HW problem?
I routed the SS signal into multilayer PCB with a correct stek up. Can the internal layer create a link problem?
Thanks in advance

Hi,
This is possibly a hardware issue. Please share the schematic and layout files for review.
