You did not tell us which STM32 model, but indeed, I just went randomly to https://github.com/STMicroelectronics/STM32CubeL4/blob/master/Middlewares/ST/STM32_USB_Host_Library/Class/HID/Inc/usbh_hid_keybd.h and lines 106, 110 and 124 all contain the same bug, so I guess this goes across all/several Cubes.

Thank you for your attention!

About the USB Host library: Is there any example of use for the HS and FS ports independently with the use of RTOS, or without the use of RTOS?

I tried to use the two ports independently, the USB HS with a pendrive (MSC) and the USB FS with a keyboard (HID), but I couldn't.

It only works if the ports are treated in sequence, but not in parallel.

From what I could see, the HAL libraries are shared, the two ports use the same HAL functions.

The same goes for other hardware, such as SPI, I2C etc.

Thank you.
