Is there a known issue with Intel xHCI controllers in SuperSpeed mode? Our FX3 based design works perfectly under several SuperSpeed controllers (Renesas, ASMedia, VIA...) but with Intel xHCI (Suface 3 pro, HP Elitebook 8570w) we have data loss in some cases and sometimes connection problems.
I read an old topic with Z77 issue and tried to disable LPM after connection, but it won´t help. Debugging with LeCroy Advisor T3 shows no errors, but the requested data from FPGA is missing in the failure case.
Edit: We work on WinUSB Driver and tested with Windows 7 and 10, both x64. It´s the same.
