Hi.

I wanted to try to program the FX3 CYUSB3KIT-001 using example from Quick Start Guide. I followed all the steps and after successful programming I do not have Cypress USB StreamerExample in device manager and the Streamer does not see it too. 

If someone could help me i would be grateful.

edit. USB 2.0 works fine, it's the problem with 3.0

I assume you have tried with default example firmware in the FX3 SDK. I see that you mentioned that USB2.0 enumeration is fine, but USB 3.0 is a problem. Can you check the device manager, please notice if you get any device on connect/disconnect of this device over USB3.0 

You can check with 2-3 different firmware, just to make sure that there is no unintentional modification which is causing this behavior.

Also, please check with a different  (working) USB 3.) cable. I suppose you are using standard cables,  (not something like a active/optical cables).
