    EZ-USB FX3 timeouts only when connected to USB3.1 host



      Our device is using the EZ-USB FX3 slave FIFO.  It works fine when connected to a usb 3.0 host.

      With a USB3.1 host (on the same PC!), there are random timeouts during bulk in (USBD_STATUS_CANCELED / error code 997).


      Now, I know FX3 does not support 3.1, but I think the host should be backward compatible with 3.0.


      cyusb3.sys version is Host application is using CyUSB.NET.


      Any suggestions?
