I’m currently powering my Comet directly from the remote machine, which works very well, except that there’s no data on the same port, so I cannot control it.
Yes, I replied before" It can be powerd by standard USB off a mini pc if you don't connet the USB port.
And once the mini pc is powered off the comet also will offline if you connect like that."
If you can set the your remote machine to keep your usb jack 5V, that will fine.
Sorry,that my explanation is not clear enouth. You can connect both the 5V power cable and the data cable to the PC. and in this situation DONT connect any device on the USB-A port of RM1.
