Standard Device Requests (cont’d)
Description
This request is used to set or enable a specific feature. The UDC
supports the Set_Feature command to set the Endpoint_Stall
feature for all supported logical endpoints and the Device_Remote
_WakeUp feature.
This request sets the device address for all future device
accesses. Stages after the initial Setup packet assume the same
device address as the Setup packet. The USB device does not
change its device address until after the Status stage of this
request is completed successfully. This is the difference between
this request and all other requests. For all other requests, the
operation indicated must be completed before the Status stage.
This request returns the specified descriptor if the descriptor
exists. The standard request to a device supports three types of
descriptors: DEVICE, CONFIGURATION & STRING. A request for
a configuration descriptor returns the configuration descriptor, all
interface descriptors, and endpoint descriptors for all the interfaces
in a single request. Class-specific and/or vendor-specific
descriptors follow the standard descriptors they extend or modify.
All Get_Descriptor requests are passed to the µC by the UDC (
refer also to
This request may be used to update existing descriptors or add
new descriptors.
This request returns the current device configuration value. If the
returned value is zero, the device is not configured.
This request sets the device configuration.
This request returns the selected alternate setting for the specified
interface. This is a valid request only when the device is in the
Configured state.
Get_Interface requests are handled by the UDC automatically, the
µC only gets a notification of it (refer also to
