Hello everybody, I am developing based on the FX3 and having troubles with Windows 8.1. I was able to limit the problem to the USBUart code used from the examples. Windows 8.1 is complaining about an invalid configuration description. So it seems to be related to the configuration descriptor. The problem only occurs if I use the SuperSpeed configuration descriptor. Under HighSpeed conditions the enumeration process completes. Any ideas? Thanks and regards Judith
