Hi to All,

STM32F4DISCOVERY board connected to SMS USB3320 HS PHY.
CPU Clock : 168Mhz from HSI.
USB Class: MSC - mass storage device.

The device descoravble by PC  I can see files on the Flash disk but when i trying to
make changes (save,open,delete .. ) the device removed and moved to unaccsseble state
(only reset helps).
I did change settings to work it as FS device MSC and no problems at ALL.

Do someone met same problem ?
Where to start looking ?
