comment Do USB devices draw current from the computer if a powered hub's current "runs out"?
Also that wasn't the question. e.g. the spec accepts a tree of hubs but the supply may still run out of Current even with less than 500mA on each device.

"in general it simply will not source more than 500mA" This is far from reality. Keyboards with 104 LEDs are known to violate the USB standard and they work almost everywhere, and in most cases that they don't, they aren't explicitly cut off but they just get the power supply to its knees.
