Error: Device enumeration failed - Error: Device enumeration failed Description If you configure and run diagnostics with the NLB_3 AFU image on Intel® Programmable Acceleration Card with Intel® Arria®10 GX FPGA . An error may occur as follows: Running fpgadiag read test... Error: device enumeration failed. Please make sure that the driver is loaded and that a bitstream for AFU id: F7DF405C-BD7A-CF72-22F1-44B0B93ACD18 is programmed.
