@Hpanda, one cannot access an external hard drive or flash drive connected to the USB-C port on any of the TMO HI 5G gateways.  If you have a router connected to your gateway, you would be able to wirelessly access a HDD plugged in the USB port.  The USB port on the gateway can be used as a power source (say, for a small fan to cool the gateway).

Not clear.   'router connected to Gateway via what?  …. USB port on gateway as power source…?  But there is only one vacant USB C port; the lower one is for power.
