Hi All,

I have developed a PCB that contains an USB3340 and a STM32F407, using the: STM32_USB-Host-Device_Lib_V2.1.0. But is allways working as a FS device instead of a HS one. I have tried the same code in the STM3240 eval board, and works really fine.

Can someone help me?? Have someone find (and solved) the same problem??

I will really appreciate some answer, because a don't know what more to do...

Thanks in advance!!

So not a software issue then, how about on a reference design using the SMSC part?

Providing a snap shot of your schematic might provide for more informed discussion.

You're not the only one. See thread 'STM32F2/F4 problams with various ULPI USB PHYs'

You can find it by seaching forums for ChirpK.
