IOCTL_SET_TIMEOUT IOCTL (usbscan.h)
Sets the time-out value for USB bulk IN, bulk OUT, or interrupt pipe access.
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.
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.
