host (Host detection)
The hub monitors the host USB socket for an attached host computer. In auto mode if the product detects a host it will change to sync mode.
The host command can be used to determine if a host computer is attached. It can also be used to prevent the hub from automatically changing modes.
Syntax: (see Command structure)

Notes
-
The presence of the host computer is still reported if the mode is set to manual.
-
On charge only products the host command is present, but as the products are charge only and cannot obtain device information the command is redundant.
-
Only the U8S can report the host to be not present as it is the only product that has a separate control and host connection.
-
The default host mode is auto for all products.
