I find it hard to believe it is a power issue since I have 9 other items plugged in all at the same time powered over usb with no issues, especially since the inspire only requires 5 watts. My current power supply is a 1600 watt corsair AX1600i 80+ titanium.
To answer your question, yes if I plug the inspire into the battery bank with the data cable into the pc it works.
On the flip side, my pc powers on the inspire with no issue, it just won’t have a connection. At this point I have submitted a ticket with revopoint for further diagnostics.
