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.

revised Why did OpenGL and Direct3D explicitly and separately transfer graphics related data to graphics memory and not blanket-map everything needed on it?

I found a workaround with round(), and I heard it's a problem with floating arithmetic. I do not know if it can be fixed.
