Does the USB standard: 1.0,1.1,2.0, specify JUST the speed of the bus?
Is the Protocol the same for all standards EXCEPT USB Hi Speed? It seems this one is NOT backward compatible to slower standard.
Are there special cables for USB 1.0 and 2.0? Specifically, can I use a 1.0 A&B cable in a 2.0 Enhanced bus architecture? It seems as though there is a 2.0 cable that will work, but has higher grade of shielding?
Can Mini A & B connectors be used in USB 1.0?
Does the Bus powered hub only provide UP TO 100mA per port UP TO 400mA total for the entire device, even if there is only 1 peripheral in the hub?
Does the Self powered hub provide UP TO 500mA PER port as an aggregate of 500mA for ALL ports or PER port regardles of the number of ports on the hub?
In other words do the devices share the total 500mA output UP TO 500mA+/- or individually up to the total ports?
Both support Daisy chain of 127 devices. What happens to the power supplied and the sharing of the bus in regards to bus and self powered when these devices are daisy chained?
Are hubs "PASS through" in USB?
