Though anything's possible, including a faulty modem, it's likely that something is actually connecting and using the data. The reps are on M-F from approximately 9AM to 6PM EST, so the earliest you'll get a reply from one in Monday.
In the meantime, it would be best to not unplug the modem, as doing so wipes the logs that can help the reps determine what is going on. If disabling the WiFi stops the usage, I would do so to ensure that you aren't burning through all of your data while waiting for a rep to reply.
BTW, if you have a satellite TV receiver and it is connected to HughesNet, that may be the culprit, as they have been known to use huge amounts of data, even if nothing is ever watched On Demand, and even when they're turned "off". DirecTV seems to be worse for this, but both DirecTV and Dish Network receivers have been known to use data.
Regarding #2, if devices are still connecting under those instances, they are likely not off, but rather in standby, and still able to connect, and something is remembering the connection credentials. Neither HughesNet, nor the HughesNet modem, has any control over how or when devices connect. If a device is connecting when it's not supposed to, the problem is with the device.
If you go to this page (while connected to modem) you should be able to see a full list of the MAC addresses of all the devices that the modem currently sees or recently disconnected from it (and when). Hopefully that can help you track down the culprit.
Depending upon how you track things, you may have to go through all your known devices for MAC addresses in order to figure out which is which. Might be helpful to keep a list.
