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
: D0h (Hub), D1h (Embedded Function)
Data
: Write 1 byte
This command is used to set the USB assigned address and enable the hub or embedded function respectively. The hub always powers up
disabled and should be enabled after a bus RESET.
