Posted on June 26, 2014 at 11:00 I haven't done this but this is how I would approach it. The initialization is done by calling the function,MX_USB_HOST_Init(). This function calls

USBH_Init(&hUsbHostFS, USBH_UserProcess, HOST_FS);

The is a matching USB_DeInit function:

USBH_DeInit(USBH_HandleTypeDef *phost)

to which you would passhUsbHostFS. Then you can re-assign your USB GPIO's as required. Worth a try.
