COMMAND DESCRIPTIONS
Command Procedure
There are four basic types of commands: Initialization, Data, Hub
Specific, and General commands. Respectively, these are used to
initialize the hub and embedded function; for data flow between the
hub, embedded function, and the host; some Hub Specific
commands for controlling individual downstream ports; and some
General commands.
Initialization Commands
Initialization commands are used during the enumeration process of
the USB network. These commands are used to enable the hub and
embedded function endpoints. They are also used to set the USB
assigned address.
Set Address / Enable
Command
Data
This command is used to set the USB assigned address and enable
the hub or embedded functions respectively. The hub powers up
enabled and needs not be enabled by the firmware at power up
initialization.
