COMMANDS

Command requests and responses are sent to and received from the device using feature reports.
Command requests are sent to the device using the HID class specific request Set Report. The
response to a command is retrieved from the device using the HID class specific request Get
Report. The requests are sent over the default control pipe. When a command request is sent,
the device will Nak the Status stage of the Set Report request until the command is completed.
This insures that as soon as the Set Report request is completed, the Get Report request can be
sent to get the command response. The usage ID for the command message was shown
previously in the Usage Table.
The following table shows how the feature report is structured for command requests:
