We use CYUSB3014 as a USB3.0 data transfer solution, which is currently in the trial production stage. Occasionally during the trial production, USB3.0 is not recognized after the board is connected to the PC.

The firmware uses the official SlaveFifoSync firmware. After the board in question is powered on and the firmware is loaded from the I2C ROM, the corresponding FX3 device can be seen in the Windows Device Manager as follows

However, at this time, the USB port cannot be recognized in the cypress control center, as shown below. The self-developed PC software can not read the port at this time.

At this point in the power state to keep re-plugging the USB3.0 cable, Windows Device Manager will pop up unrecognized USB devices, as follows

Can you tell me whether this problem is a hardware failure or a firmware failure and how to troubleshoot and solve it.

cyusb3014, after plugging into the usb2.0 interface, which functions in cyapi.lib are called by the software to complete the initialization, read and write operations?

Refer to fx3 sdk 1.3.5 routine uac_examples to modify fx3 to usb Speakers, the computer recognizes the device, but the computer can't play the audio properly and the fx3 can't receive the audio data. May I ask what is the problem? Is there any related routines I can refer to? #EZ-USB FX3
