| PFNUSBCAMD_BulkReadWrite |
The USBCAMD_BulkReadWrite service performs a read or write operation on the specified bulk pipe. |
| PFNUSBCAMD_CancelBulkReadWrite |
The USBCAMD_CancelBulkReadWrite service cancels a pending bulk read or write request. |
| PFNUSBCAMD_SetIsoPipeState |
The USBCAMD_SetIsoPipeState service permits the camera minidriver to control the streaming state on the isochronous pipe. |
| PFNUSBCAMD_SetVideoFormat |
The USBCAMD_SetVideoFormat service is used to notify USBCAMD that the video format has changed. |
