The IOCTL_USBIO_SET_PIPE_PARAMETERS operation is used to
set USBIO parameters related to a pipe.

lpInBuffer

Pointer to a buffer that contains an USBIO_PIPE_PARAMETERS
(

page 208

) data structure. This data structure has to be filled completely

by the caller.

nInBufferSize

Specifies the size, in bytes, of the buffer pointed to by

lpInBuffer

which has to be sizeof(USBIO_PIPE_PARAMETERS) for this operation.

lpOutBuffer

Not used with this operation. Set to NULL.

nOutBufferSize

Comments

The default state of the pipe parameters is defined by a set of registry
parameters which are read by the USBIO driver at startup. The current
state can be modified by using this request.
