Hello, you may remember STM32F2 and F4 had troubles with some HS-USB ULPI transceivers from Microchip. I wonder if these issues exist with STM32F7 too ? I'm especially interested in USB3317 and USB3343. I've noticed the Discovery board uses USB3320 but the previous two are smaller packages, easier to integrate and do not need external ESD protection. Thank you !

I've just stumbled on a presentation from ST titled : ''USB OTG v2.x'' which introduces improvements in L4/F7 over F2/F4 and contains this sentence : ''For HS embeds ULPI interface fix to support new SMSC PHYs''.

I have no better source than either :http://comm.eefocus.com/media/download/index/id-1004375http://wenku.baidu.com/view/c3214480ba1aa8114531d984.htmlThis looks promising but would anyone have tried the USB331x or USB334x series ? Thank you.
