5.3.1 Host Commands and Hub Answers
An USB hub needs at least 2 endpoints to guarantee the normal operation. Endpoint 0 is the default control
pipe. Endpoint 1 is the interrupt pipe.
Host gets all the information about the hub and through the control pipe. Hub information like self/bus
power and gang/individual mode is all replied to host via endpoint0. Interrupt pipe is to report to the host
the updated change of hub status (power change and over current change, for example) and the updated
status change of all downstream ports (connect change, suspend change, over current change, etc.).
