Windows Driver Kit DDI reference (ni-usbscan-ioctl_set_timeout)

Description

Sets the time-out value for USB bulk IN, bulk OUT, or interrupt pipe access.

Parameters

Major code

Input buffer

Pointer to a USBSCAN_TIMEOUT structure.

Input buffer length

Size of the input buffer.

Output buffer

NULL.

Output buffer length

Zero.

Input/output buffer

Input/output buffer length

Status block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful. Otherwise, Status to the appropriate error condition as a NTSTATUS code.

Remarks

DeviceIoControl Parameters

When the DeviceloControl function is called with the IOCTL_SET_TIMEOUT I/O control code, the caller must specify the address of a USBSCAN_TIMEOUT structure as the function's lpInBuffer parameter.

Using the USBSCAN_TIMEOUT structure's contents, the kernel-mode driver resets the time-out value for each type of operation: bulk IN read, bulk OUT write, or interrupt.

For more information, see Accessing Kernel-Mode Drivers for Still Image Devices.

The default time-out value is 120 seconds. The maximum time-out value is 214 seconds. Values greater than 214 seconds will cause transfer time-outs.
