Hi,

I am working on a STM32F207 micro controller on a personal Borad.

I use 2 USB

- A usb OTG on internal phy of pin PA9, PA10, PA12 andPA13 with a mini AB connector

This is the same use onthe eval board

- A usb Host on the second internal phy onpin PB13, PB14, and PB15 on a classic A connector

This is not thesame use than the eval board where ST use an ULPI external phy

I ported the MSC host example codefrom V2.0.0/ 22-July-2011

If I use an adaptator for mini AB to A for my USB key everything works on the first USB.

On the second usb the enumeration is OK but the programm is locked when it try to explore the disk.

I use the compilation option USE_USB_OTG_HS and USE_EMBEDDED_PHY

Is it possible that there is a mistake on the USB driver because this phy can not be tested on the eval board ?

Does anyone have succefuly use this internal phy ?

Thanks
