Hi All

I have a question regarding CYUSB3304-68LTXC, is there anyway to disable USB 2.0 functionality?

Looking at the datasheet I can only see a way to disable USB 3.0 functionality

Hi,

There is no direct option to disable the USB 2.0 part of the hub on the upstream port but you could disable the functionality on the individual downstream ports using the Blaster Plus utility. Please refer to the attached snippet.

You could also leave the USB 2.0 lines unconnected on the upstream port so that only the USB 3.0 part of the hub enumerates.

Best Regards,
Sananya
