Other Parts Discussed in Thread: TUSB320
Provide case details or comments: We expect the TUSB320 to become a sink when it is connected to an OTG device.
We do have the rare case, that the USB320HAI forces source mode, when it should not.
Our device connects with USB-C to a mac book and sometimes it does not enumerate as a sink but does source the mac book.
We do not see this behavior on other laptops.
SRC50.png shows a good case. we connect to a Mac book power direction is negotiated twice (we have set the try.SNK bit on the TUSB320)
but sometimes we end up with case SRC51.png, where the TUSB320 turns VBUS on and goes to source mode.
We do not understand why the TUSB320 does not wait for CC_debounce ?
We assume the Mac refuses to be a source, because VBUS is still too high. But we have plots, where it seems to respect the timeouts and than it turns on in the right mode. See SRC39.png
