How to monitor USB power consumption

logspowerusb

I'm looking for a way to monitor the power being drawn from the USB ports on my Mac.

System Profiler doesn't appear to display this and I haven't been able to find any applications or tools to do the job either.

Can anyone suggest anything (preferably software based)?

USB power consumption information should be available in System Profiler. See the screenshot below:
