Its descriptors claim that it wants 0 mA.
But it's delivered by default with a two-host-plug
USB cable
So it needs more power than a single plug could supply?
and would not be able to know about the power
available from the
power-only plug. And it doesn't complain when running from the analog
input either, so it would be somewhat strange to just shut down when in
USB mode.
After a short time, it just stops reacting to USB requests.
It might be possible that some capacitor does no longer work correctly,
and that its internal voltage drops too far when actually doing things.
This would imply that it doesn't work in Windows either.
