7.4 USB Interface and Device Control
The W9967CF contains two endpoints: default and Video Data-In endpoints. Figure 7.3 shows the
device configuration for the W9967CF-based USB digital video camera.

7.4.1 Endpoints
7.4.1.1 Default Endpoint (Endpoint 0)
The default endpoint uses control transfers as defined in the USB specification. The default endpoint
provides access to the W9967CF-based device
′
s configuration, status, and control information by
sending standard, class, and vendor-specific requests to the device, an interface, or an endpoint.
7.4.1.2 Video Data-In Endpoint (Endpoint 1)
The Video Data-In endpoint is used to receive video image data from the device intended for delivery
to a video capture application on the host. The Video Data-In endpoint uses isochronous transfers.
The direction is always IN. The maximum packet size can be varied for different alternate settings for
limited USB bandwidth.
7.4.2 USB Device Requests
The W9967CF responds to requests from the host on the default pipe. The W9967CF supports
standard, class, and vendor-specific USB device requests.
7.4.2.1 Standard Device Requests
The W9967CF supports the standard USB device requests as shown in Table 7.3 and described
below. It responds to standard device requests whether it has been assigned a non-default address or
is currently configured. If any unrecognized or unsupported standard request is received, it returns
STALL.
