I do use a FT2232H with the driver from CDM21228_Setup. It is used for a SPI connection to some target.
Next to this I do use an STM32-H405 for a special single wire connection.
Both drivers are installed and always shown as working on driver level in windows device manager.
I did use the STM32-H405 first for a test sequence without any problem. The USB-Description is shown in STMicroelectronics Virtual COM Port - com6.txt as given by USBTreeView. I did use the FT2232H Interface with another Windows application for some testing. After usage of this connection, the connection on the other interface via STM32-H405 is broken and locks completely for the application. The USB-Description for the interface is changed to what is shown in STMicroelectronics Virtual COM Port - com6 - 2.txt.
The USB-Description of USBTreeView for the FT2232H stays nearly the same before and after the run as shown in USB-Verbundgerät -com7,com8.txt and is still usable for another test.
