Description

A pointer to a SINGLE_TRANSFER structure is passed to the driver for the IOCTL_ADAPT_SEND_NON_EP0_TRANSFER and IOCTL_ADAPT_SEND_EP0_CONTROL_TRANSFER commands.

The structure is defined as:

typedef struct  _SINGLE_TRANSFER {

union {

  SETUP_PACKET    SetupPacket;

  ISO_ADV_PARAMS    IsoParams;

};

UCHAR Reserved;

UCHAR ucEndpointAddress;

ULONG NtStatus;

ULONG UsbdStatus;

ULONG IsoPacketOffset;

ULONG IsoPacketLength;

ULONG BufferOffset;

ULONG BufferLength;

} SINGLE_TRANSFER, *PSINGLE_TRANSFER;

Members

SetupPacket

         Contains required parameters for Control Endpoint transfers,

IsoParams

   Contains optional parameters for Isochronous Endpoint transfers.

reserved

   Reserved. Should be set to 0.

ucEndpointAddress

   Specified the address of the device endpoint in which the transfer will occur.

NtStatus

   NTSTATUS values that are returned by the driver.

UsbdStatus

   USB_STATUS_XXX codes returned from the host controller driver.

IsoPacketOffset

   Specifies the byte offset from the beginning of the structure to an IsoPacket list.

IsoPacketLength

   The length, in bytes, of the IsoPacket list specified at offset IsoPacketOffset.

BufferOffset

   Specifies the byte offset from the beginning of the structure to a transfer buffer.

BufferLength

   The length, in bytes, of the transfer buffer at offset BufferOffset.
