I still don't get why USB_OTG_DRV_VBUS exists, as well as the

any fixed setting hardly makes sense...
Hmm. I thought this lets you decide whether you use the internal
pulls or use external ones.
And you were right -- 1.5K Ohm pullups are used on device side to
signal the speed. Host side does use 15K Ohm pulldowns. I've mixed
everything up, so rry about that. :-)
How would the OTG core alter the behaviour
then? Which code would be missing to support it the way the OTG stack
works?
I don't have the OTG spec. at hand (or in any digital form), and my
memories of the reading are fragmented ATM... :-/ Will try to gfet my
hands on the printout again...
Well, still not clear about the ID pullup/sampling -- do you want to
be able to suppress that fro the board code too? Without this, it's
basically not OTG anymore.
Thanks,
Daniel
