Still image USB I/O structures
The following table lists and describes all of the structures associated with the I/O Control Codes recognized by the kernel-mode still image driver for SCSI buses.
| Structure | Description |
|---|---|
| CHANNEL_INFO | Used as a parameter to DeviceIoControl, when the specified I/O control code is IOCTL_GET_CHANNEL_ALIGN_RQST. |
| DEVICE_DESCRIPTOR | Used as a parameter to DeviceIoControl, when the specified I/O control code is IOCTL_GET_DEVICE_DESCRIPTOR . |
| DRV_VERSION | Used as a parameter to DeviceIoControl, when the specified I/O control code is IOCTL_GET_VERSION. |
| IO_BLOCK | Used as a parameter to DeviceIoControl, when the specified I/O control code is IOCTL_READ_REGISTERS or IOCTL_WRITE_REGISTERS. |
| IO_BLOCK_EX | Used as a parameter to DeviceIoControl, when the specified I/O control code is IOCTL_SEND_USB_REQUEST. |
| USBSCAN_GET_DESCRIPTOR | Used as a parameter to DeviceIoControl, when the specified I/O control code is IOCTL_GET_USB_DESCRIPTOR. |
| USBSCAN_PIPE_CONFIGURATION | Used as a parameter to DeviceIoControl, when the specified I/O control code is IOCTL_GET_PIPE_CONFIGURATION. |
| USBSCAN_PIPE_INFORMATION | Used to describe a USB transfer pipe for a still image device. |
| USBSCAN_TIMEOUT | Stores time-out values for USB bulk IN and bulk OUT operations, and interrupts. |
