Hello
Recently i try to update to the latest cypress driver with CYUSB3_1.3.0.2_21H2_x64_MSFT_Signed.zip from this link
https://community.infineon.com/t5/USB-low-full-high-speed/Win10-specific-issue-in-data-transfer-from...

After successful driver update, we verify from device manager and it is updated to 1.30 version and enable the window to signed startup. We could not able to receive any data with this driver.

We are running with window 10 64bits. However if i downgrade back to cyusb3_win10_x64_1.2.3.25, we can received data from FX3 again.

Is there any steps i need to do in either firmware/software to use the latest driver? We are using C++ CYAPI for our software.

Thanks

  2. Error which you getting while using latest driver version
    -> I could not receive any data using xferdata().
  3. Please confirm the transfer size. Is it greater than 4MB?
    -> Yes, it is greater than 4MB, even i request less than 4MB it do not work as well
