Hi,

I assume you're asking why there is a disconnect followed by connect once the firmware is downloaded and whether it is due to device or due to driver?

Is my understanding right?

Regards,

Anand

Most probably the signal quality of your cable isn't good. The device is trying to enumerate in SuperSpeed but not able to and keeps trying again and again. Is the cable you're using USB certified?

Just to make sure the FX3 chip on the board is good and the firmware is running properly please modify one of the examples to enumerate in high-speed and check if it enumerates successfully.

Regards,

Anand
