Programatically getting USB power draw of a device?

Question

In Windows, it is possible to view a Power tab for a USB hub in Device Manager that lists information such as whether the hub is self-powered and the total power available.

Is this information available programatically, either in Windows (perhaps WMI?) or Linux? I've looked in MSDN with little success so far.

Answer 1

Does this help you?

Answer 2

I think WMI is going to be your best bet here. I'm not familar with exactly what you want, but I'd start with the Win32_VoltageProbe class.

Answer 3

Linux:

lsusb -v | grep MaxPower
