I replace the Device Library v2.53 in cubemx 6.4 with this version for custom HID on STM32F303RC. The STAT_RX[1:0] in USB_EP1R is 11 (VALID) before reception transfers. When PC send out only one byte to device，the STAT_RX[1:0] in USB_EP1R is always 10 (NAK) and PC can not send out any data to device (STM32F303RC). This case does not be appeared in Device Library V2.53.

Hi i am trying to start a project but in the CubeMx while initializing connectivity and USB device middleware i can not see other types billboard and etc, could please help me to sort out this problem, Thanks

What is the class that you need? The free ST library is limited, it does not contain all known classes. But it is free.

Hi Pavel A,

Thanks for your response, i am looking for USB Device CCID class specifically.

Hello,

are there any examples of USB composite devices in the pipeline? According to the current STM32CubeProjectsList.html, there are examples for several USB classes in one project, but it seems that these are examples that use different USB ports. At this time, I can't estimate the effort to integrate multiple USB classes on one port as a composite device.
