STM32F407 USB_OTG_HS/CDC flash origin issue

Question asked by Sergey Titov on Oct 17, 2017

We have project generated in STM32CubeMX v.4.21.0 based on STM32F407VETx  MCU. This project use USB_OTG_HS to communicate with host computer. When we write program to flash at origin value ORIGIN = 0x8000000 all works fine. But when we set flash origin to 0x8020000 all works except CDC driver. Windows 10 reports driver error code 10, on linux lsusb reports "Couldn't get configuration descriptor 0". Anyone encountered such a problem?
