Hallo everybody,


i have a problem with the communication between a USB CDC Device and the PC Software Labview.


On the pictures below you can see my cube settings and labview settings.


When i try to open the virtuell com port with a terminal programm there is no fail.


But when i try to open the com port with Labview there is very often a fail message.

I don't know what's the reason of the problem.

Other virtuell com port devices doesn't have this problem.


I have 8 pcb boards. Two with STM32F429BIT and Six with STM32F767BIT.

All have this problem.

On some boards this error almost always appears.

On other boards this error appears rather rare.
