    Teensy 3.6 USB Host -> USB Hub -> voltage monitor only showing 3.6V?

    Hi!

    I have a Teensy 3.6 with the USB Host port going to a 4-port USB Hub (this one https://www.modmypi.com/raspberry-pi...-uk-plug-5v-2a).

    I have this setup: PC-> (micro usb)-Teensy-(USB Host port) -> USB Hub -> USB Voltage/Current monitor

    I'm only getting ~3.6V on the monitor end, which doesn't seem right to me. The USB Hub is good with all other connections.

    Is this where I need to do something with the D/H pads under the Teensy?

    Could I just connect VIN to USB Host +5V?

    FYI the USB Hub supports external power, which I will be using if any of the devices require more current.
