I'm glad I found this thread. I was doing all kinds of testing, killing myself, trying to figure this out this problem

But I found since the latest software upgrade, I don't need an extra cable or do any weird modifications. While testing with various different USB power supplies and different cables, I found that nearly every time, All I needed to do was connect the USB cable (which would do nothing), unplug the USB cable and then plug it back in. The second time I plug in the USB cable the device detects the power supply and works....

It would still be better if the device would work on the first instance of plugging in the cable, but it is a relatively small inconvenience.

Thanks
Bob
