The version referenced in the thread - Link is 1.3.0.2.
Is it built with /CECOMPAT compiler option?
I need release notes to be able to include it in production build.
What FX3 SDK does include it?

Thanks,
Leonid

Hello Leonid,

it is not built with CECOMPAT option.
This version of the driver is not released with SDK, so we don't have a release note for this now.

Hi Biren,

Thank you for clarification.

HLK hardware-enforced stack protection test is asking weather:

  1. Driver is compatible with HSP (no return address hijacking)
  2. Driver has been compiled with /CECOMPAT flag

Type "Y" if above is true, or "N" if the above is FALSE.

Will it affect Windows 11 driver signing?

Thanks,
Leonid

Hello Biren,

When I'm running our application with CyUSB3.sys version 1.3.0.2,  our device continuously disappears and comes back in Device manager.

It works fine with version 1.2.3.20 that is currently available with EZ-USB FX3 SDK. Is there any difference in API between these two versions?

Thanks,
Leonid

Hi Meghavi,

Firmware is proprietary one and in use for 6 years.

USB 2.0 bulk.

Hi Leonid,

We have tested a default bulkloop example with cyusb3kit-003 kit  using the latest driver 1.3.0.2v. It is working fine on windows 11 pc. Can you please share the USB traces with us?

Meghavi
