The only computers I've seen complaining about USB current consumption is 
Macs, both desktops and laptops, and running both OS X and Windows. You get 
this nice loop where the OS turns off the host port, pops up a warning

pops up another dialog etc. I was still dismissing dialogs for almost a 
minute after yanking out the device.
