Port Re-Mapping Enable (PRTMAP_EN)
Selects the method used by the Hub to assign port numbers and disable
ports.
0 = Standard Mode. The following EEPROM addresses are used to define
which ports are enabled. The ports mapped as Port’n’ on the Hub are
reported as Port’n’ to the host, unless one of the ports is disabled, then the
higher numbered ports are remapped in order to report contiguous port
numbers to the host.
EEPROM Address 2Ah: Port Disable for Self-Powered operation
EEPROM Address 2Bh: Port Disable for Bus-Powered operation
1 = Port Re-Map mode. The mode enables remapping via the following
EEPROM addresses:
EEPROM Address 36h: Port Remap 12
EEPROM Address 37h: Port Remap 34
EEPROM Address 38h: Port Remap 5
