USB over current issue

Hello,

I am debugging USB function on STM NUCLEO-H723ZG demo board. I set the USB_DEVICE Mode as CDC(Virtual Port) mode. USB_OTG_HS can as below.

Now I can get the virtual port number on the computer. But the VBUS over current LED (LD7) is always on. It indicates the VBUS over current. But I have configured the EN pin of STMPS2141STR as high (Set PD10/USB_FS_PWR_EN) to disable this fault. 

Can anyone please help to check what’s the problem? Thanks,

Problem fixed. I set USB_FS_OVCR(PG7) pin by mistake.
