Set_Port_Feature
Set_Port_Feature sets a value reported in the Hub Control-
ler’s port status. The AT43310 supports all USB required
features. Note that only the relevant Set Port commands
are supported (see SET_PORT Features Table). For
example, the PORT_LOW_SPEED value is determined by
the operation of the port of the attached device. Upon an
invalid request (e.g. a Set_PORT request for
PORT_LOW_SPEED), the AT43310 will return a STALL
status to the host.
