1.3.1.2
This file contains the USB descriptor information for the device. This information varies
based on the application.
A typical configuration descriptor consists of these components:
• At least one configuration descriptor
• One or more interface descriptors
• One or more endpoint descriptors
In addition, there is usually a descriptor string that provides a plain text description of
the device.
1.3.1.2.1
The bmAttributes object of the configuration descriptor can be modified to meet the
needs to the specific application. The available options are shown in Table 1-1. The
selected options should be ORed together to form the corresponding entry (e.g., a
device with all of the options should have “_DEFAULT | _SELF | _RWU”).
For more details about the configuration descriptor, please see Table 9-10 of the USB
specification.
TABLE 1-1:
1.3.1.2.2
Both the bEndpointAddress and bmAttributes field of the endpoint descriptors
have definitions available in the stack to select the various options. The options should
be ORed together to form the desired set of options. The available options are shown
in Table 1-2 and Table 1-3.
More information about the endpoint descriptors can be found in Table 9-13 of the USB
specification.

Required definition that sets the reserved bits of this attribute as
required by the specification.
Designate this device as a self-powered device.
Designate this device as having remote wake-up functionality.
Defines the endpoint as an IN endpoint. This definition must be ORed
with the endpoint number to form the required value (e.g.,
MY_ENDPOINT_NUMBER | _EP_IN).
Defines the endpoint as an OUT endpoint. This definition must be
ORed with the endpoint number to form the required value (e.g.,
MY_ENDPOINT_NUMBER | _EP_OUT).
Defines the endpoint as an OUT endpoint where <xx> is the endpoint
number. No other definitions are required.
Defines the endpoint as an IN endpoint where <xx> is the endpoint
number. No other definitions are required.
