There was a change to the Linux kernel that broke abandonware/bluetooth-hci-socket (see abandonware/node-bluetooth-hci-socket#60).
This means node-poweredup doesn't work anymore on Linux. I tried switching to the Noble fork from stoprocent (see the last comment in that link above) but that doesn't seem to work properly either - the hubs can be discovered, but they rarely connect properly. For example, the sample code in the readme.md file just prints the "Discovered" message but not the Connected message; then the hub shuts down and then eventually an error ("Command Disallowed") is eventually printed before the program terminates.
