USB Host does not detect flashdisk plugin and no interrupt occurrence

[runbaby]

I am use Nucleo-H563Zi test the usb host feature, I connected the USB_USER jumper to provide VBUS, and just use 2 wire usb, ignore 2 CC line. and configed in cubeide as below

Then I generat code, and I add 

"HAL_HCD_Start(&hhcd_USB_DRD_FS);"

before while(1)

then compile and debug the program

but I can not detect the flash disk plugin and no usb interrupt occure.

what config is wrong for this test.

Thank you.

find the reason, we need enable USB33SV in register PWR_USBSCR, and this implement in HAL_PWREx_EnableVddUSB(), and was not generate by cubeide,  we need add this function call manually,

after that it works good.
