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.

Linux:
lsusb -v | grep MaxPower

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.
