The class code would not explicitly learn about the reset,

That has drawbacks
Playing devils advocate a bit here
- it doesn't tell you what caused the mode to be left (if you
UFP, it may be the regular command)
Does it matter ?
- it is a race against your own command
It is my understanding that races have to be resolved by the drivers,
since the typec code does not do any locking. This is quite similar
to handling, say, a request to change the vconn source or to change
the power role. Am I missing something ?
- it does not work if you are in basic USB mode
Would alternate modes be active in that case ?
Thanks,
