SrinathS_16 Dec 7, 2018 1:46 AM (in response to eagle252525_1526501)Hello,
- Have you implemented a vendor command handler to communicate over the Control endpoint?
- To notify the FPGA, you can toggle/drive a GPIO from the FX3 inside the vendor command handler. Please look at the CyFxApplnUSBSetupCB() function block in the GpifToUsb example firmware that comes with the FX3 SDK for reference implementation of vendor commands.
Best regards,

- In case you are using FX3 in USB 2.0 mode, please refer to the below KBA which has got the workaround.
EZ-USB® FX3™ Issues With Simultaneous Bulk-IN and Control-IN Transfers In USB 2.0 – KBA92475
- In case you are using USB 3.0 mode and still face issue, please capture the USB traces during failure and share the same.
