Usb Host Support for STM32F family

qu1: Does the mbed USB host support the F401RE 2USB otg?

<br>The board Nucleo-F401RE doesn't support USB Otg connectors directly, but could be hand wired to support two USB micro-AB.

mbeb has USB Host support

  • qu 2) does this support the two USB Otg of the F401RE
  • Elsewhere in the Cube4 documents and UM1720 the USB Host Libray is discussed.
  • qu 3) is this the same, or better/worse then the mbed USB Host support
  • qu 4) Do you recommend doing my own evaluation using the Nucleo-F401RE on mbed and STM32FDiscovery with Cube4 ?

The official USBHost lib is sadly/strangely/weirdly still only for the LPC1768. However a user made a USBHost lib which should work on the F401: https://mbed.org/users/va009039/code/F401RE-USBHost/ (Btw despite its name it is not only F401, also the Freescale ones are supported).

Is there a plan to update the USBHost library so that it can support the numerous Nucleo boards? With recent mbed library updates, the library developed by the user mentioned above (https://mbed.org/users/va009039/code/F401RE-USBHost/) does not even work anymore with the F401RE. My personal interest is for F401RE and L476RG. Thanks.

I am not mbed staff. Who knows if it ever happens, but I wouldn't wait for it. It hasn't happened in the last years.
