USB_OTG_FS on the STM3240G-EVAL?

I can't get USB_OTG_FS communication to work on the STM3240G-EVAL board. USB_OTG_HS works with no problem. I tried disabling HS using JP31, but ST's example application still can't reach the USB_OTG_FS.

I thought this might be caused by a defective board, but the second board we bought has the same problem. So I suspect there's a simple reason for this. Has anyone gotten this to work?

Don't have the board, but would suggest you try and compile some of the other example projects in the USB FW library.

I downloaded the USB Host-Device Library from ST and compiled the MSC example for USB devices. But when I loaded it onto the board, the OTG_FS connection didn't respond. I used the following flags: -DUSE_STDPERIPH_DRIVER=1 -DSTM32F4XX=1 -DUSE_STM324xG_EVAL=1 -DUSE_USB_OTG_FS=1

My USB protocol analyzer tells me that the device simply timed out. Well, at least the OTG_FS connection on the Discovery board works.
