STM32 F7 USB host is failing to detect USB drive with new STM32 HAL library(V.1.2.8)

Hi, We have implemented USB bootloader for our project(Using STM32F7). We are using ST HAL libraries for our bootloader implementation. It was working fine fine with V1.2.7 and we are facing issue after migrating to new HAL i.eV1.2.8.
