Universal Serial Bus Interface
16.9.6.2.2
After the port change interrupt indicates that a port is enabled, the EHCI stack should determine the port
speed. Unlike the EHCI implementation which will re-assign the port owner for any device that does not
connect at High-Speed, this host controller supports direct attach of non-HS devices. Therefore, the
following differences are important regarding port speed detection:

Port owner is read-only and always reads 0.
A 2-bit port speed indicator has been added to PORTSC to provide the current operating speed of
the port to the host controller driver.
A 1-bit high-speed indicator has been added to PORTSC to signify that the port is in HS vs. FS/LS
