usb msc host or msc device dynamic selection.

SKIM.6 · ‎2023-03-21

I want to configure a USB device using STM32F746.

I want to select the USBH MSC Host and Device as needed (without rebooting..).

In CubeMX, only "Host Only" or "Device Only" can be selected.

When selecting DualRole in CubeMX, a library is not created.

I want to dynamically select and use the USBH MSC Host and Device.

Please let me know if there is a way.

You go from one state to other through a XXXDeInit()/YYYInit() cycle, there is no more to it.

Now how well do DeInit() for USBD/USBH work in Cube, I don't know, I don't use Cube.

Don't waste your time on a broken bloatware and use an USB stack developed by competent people:
