After a further explanation of USB physical port numbers from John 
Sandford  I concede that this line of enquiry into why Back Outer USB 
socket doesn't boot-up properly in ROM512 is a red herring, and will 
not shed any light on that problem.

[So the fact that Back Outer USB socket doesn't boot-up properly [even 
when an Iyonix mouse and an Iyonix keyboard are used] seems to be 
still an un-re-solved problem in ROM512].
