What about OTG and gadget modes?
The MUSB hardware is flakey with respect to those init issues. Re-ordering host vs gadget init has been a good way to waste a few months, for anyone who has a few to waste. (And a better way to waste them for folk who do NOT but just need to stay on schedule.) One learns quickly that the Mentor IP follows some other state machine than the USB-OTG says, but even their docs don't help uncover whatever init model they are trying to follow.
