Remarks
DeviceIoControl Parameters
When the DeviceloControl function is called with the IOCTL_GET_PIPE_CONFIGURATION I/O control code, the caller must specify the address of a USBSCAN_PIPE_CONFIGURATION structure as the function's lpOutbuffer parameter. The kernel-mode driver fills in the structure.
