    If you are brave enough, you could see what UHS3.0 does when it sees it connect. --- just don't use a hub, that's broken right now. You may find that it contains several interfaces, one of which could possibly be a...

    Ahhh... and this is why I made HID device in UHS3 agnostic as to what exactly is attached. Note that recent Teensyduino broke UHS3... not sure why exactly yet, but I have been working on finding out why. *should*...

    No, the idea is to catch the firmware upload, and shutdown external devices when we _know_ we are going to reboot, which is different than not knowing. The startup hook isn't going to work, that's too late, and would...

    Depends if you actually follow the standard, or invent your own. If you are connecting to something that is a "standard" then there isn't much I can do to help. I usually treat CAN like serial, but with the ability...
