I am using STM32Cube_FW_F4_V1.21.0.This is very excellent software.UART,SPI,I2S,RTC,,,work fine but HS-IN-FS.
I have checked HS and FS works fine.
My target board is STM32469I-EVAL board and I'm using EWARM compiler suite.
My application is USB_Device/MSC_Standalone.
(I used HS-IN-FS workspace file so USE_USB_HS and USE_USB_HS_IN_FS are defined properly)
I run without any change,I can built program without an error.I downloaded and executed.
and program reached while(1).I connected USB cable to (CN14) but windows explore was not able to find mass strage device.
USB related registers were set below.
GOTGCTL= 3010000
GOTGINT=100000
GAHBCFG= 1
GUSBCFG=40001440
GRSTCTL=80000000

Looks like DCFG register is incorrect.DSPD[1:0] = 11 means Full speed to work with internal FS PHY.
So I modified usbd_conf.c and stm32xx_ll_usb.c to select Full speed using HS.
After modification,I tetsted.Program.But It still has problem.
register were set below.

ENUMSPD bit in DSTS register was 01,means reserved.So I was not able to connect to Windows explore.
Could you teach me how to set up these registers ?
If you have workaround software,please provide me.
If you need more info,let me know.
Best Regards,
Thank you.
