Hello,
working with USB Device, i discovered that, the most important
manufactures of the motherboards, don't monitoring the USB current draw.
The +5V of the USB is directly connected to the +5V of the Power Supply
(there is only a fuse/polyswitch)
So, all motherboards aren't compliance to the chapter 7 of the USB
Specifications!
Do You know some motherboards that control the current over the +5V USB
supply and so can limit the current to 100mA?
(in the enumeration process or in a possible overcurrent situations)
What do You think about it?
