We haven;t witnessed any such issues with Intel xCHI controllers, other than LPM.
Do you face the sae issue with any of our example projects with cyusb3 driver? If not, it should be related to winUSB

I solved the problem for now. I crawled the code examples and figured out my mistake. I placed the DisableLPM on the wrong place in the firmware. Now it works correctly also with Intel xHCI.
Could you please point out where in the firmware did you correctly place DisableLPM?
I am facing data loss with xchi_hcd on 4.12 kernel on Ubuntu 16.04 using libusb.
