Can the OTG_HS_DM and OTG_HS_DP pins be used for USB full speed operation?

[TCour.1]

On page 186 of the datasheet for the STMF407xx the diagram for using USB FS shows that the pairs PA11/PA12 (OTG_HS) or PB14/PB15 (OTG_FS) can be used to connect the USB DM and DP lines. However, the pinout table on pages 52 & 55 explicitly list the functions of PB14/PB15 to be OTG_HS and PA11/PA12 to be OTG_FS.

Can pins PB14/PB15 be used for USB FS operation as indiciated by the diagram on page 186 of the datasheet? It doesn't need to appear in windows as either FS or HS, it just needs to work. Thanks

"OTG_HS" is name of module capable of HS only with an external HS PHY, but it also does have an internal FS PHY brought out to the given DP/DM pin pair.

In other words, you can have two completely independent FS connections directly from one 'F407.

Awesome, thanks so much for your reply!
