![]() ![]() If the issue is signal quality, then sometimes a HUB in-between can help or hurt.Most charger cables would be able to detect device mode, but would fail during sustained data transfer. The micro-B cable provided with the dev kit is very good quality.For various reasons this might fail even if the hardware is good. A running Jetson has a default sample of both a network interface and mass storage (read only).Similar if mass storage is not automatically allowed. For example, there may be settings to say to not use network adapters as a network device until ok’d. Security and other local settings can get in the way of using a device mode USB port.Windows does not know how to work with this custom device (recovery mode). Being able to see recovery mode is a good test of hardware function. This should never fail, otherwise it implies hardware error. By default a Jetson shows up as a custom device when in recovery mode.OTC accepts either, which is why the detect pin is needed. What shows up is completely custom to any computer which implements a B type connector.For the micro-B, device mode is triggered by the correct micro-B cable ID detect being seen by the Jetson.The port will only show up if it is in device mode.Before asking more, some USB info might be useful:
