Good afternoon,
We're using the USB3 port on the LTE I/O expansion board, and have it connected via a hub to 4 devices - one storage and 3 cameras. It sometimes works, but the port is unreliable at best, and totally unusable most of the time. We've tried going through passive hubs, powered hubs, and a $400 optically decoupled hub - all yielding the same results; it appears to sort-of work until you actually go to use it, at which point everything downstream of that port just disappears. It will occasionally sporadically start coming back, but not reliably enough to do anything useful. Any ideas?
A week ago, this was all largely working, though the week before it was not. We never did figure out why it suddenly started working again, and certainly don't know why it stopped.
Thanks!
