Hi Sir,
A very Good Day to you !
The customer's product is an industrial camera, which uses cyusb3014-bzxc. When performing ESD 4KV test, no data will be sent out from CYUSB3014. The following figure is detected by bushound.All the control commands sent from the host failed, and the reset device can be used to restore normal operation.How to solve this problem?
Best regards!
Paddy

Hi,
1. Are you doing contact discharge or air discharge?
2. The location of on the board where you are firing the charge gun?
3. Have you provided ESD protection diodes on USB lines?
4. Could you please provide the schematic of your design.
Please check if you are getting CY_U3P_USB_EVENT_EP_UNDERRUN - you can check it in USBEventCB().
>If yes, you can implement the handling which is there in GpifToUsb example and test for response from device.
Please implement USB logging as implemented in USBBulkSrcSink example of FX3 SDK and share the UART log.
Regards,
Hemanth
