Port indicator support
Multiple ganged power mode is reported as individual power mode; refer to Universal Serial Bus Specification Rev. 2.0.
When the hub uses global overcurrent protection mode, the overcurrent indication is through wHubStatus field bit 1 (overcurrent) and
the corresponding change bit (overcurrent change).
Configuration parameters
The ISP1521 is configured through I/O pins and, optionally, through an external I
in which case the hub can update its configuration descriptors as a master or as a slave.
