Submits an interrupt transfer to an interrupt endpoint of a USB device.
@param Ohc Device private data
@param DeviceAddress Represents the address of the target device on the USB,
which is assigned during USB enumeration.
@param EndPointAddress The combination of an endpoint number and an endpoint
direction of the target USB device. Each endpoint address
supports data transfer in one direction except the
control endpoint (whose default endpoint address is 0).
It is the caller's responsibility to make sure that
the EndPointAddress represents an interrupt endpoint.
@param IsSlowDevice Indicates whether the target device is slow device
or full-speed device.
@param MaxPacketLength Indicates the maximum packet size the target endpoint
is capable of sending or receiving.
@param IsNewTransfer If TRUE, an asynchronous interrupt pipe is built between
the host and the target interrupt endpoint.
If FALSE, the specified asynchronous interrupt pipe
is canceled.
@param DataToggle A pointer to the data toggle value. On input, it is valid
when IsNewTransfer is TRUE, and it indicates the initial
data toggle value the asynchronous interrupt transfer
should adopt.
On output, it is valid when IsNewTransfer is FALSE,
and it is updated to indicate the data toggle value of
the subsequent asynchronous interrupt transfer.
@param PollingInterval Indicates the interval, in milliseconds, that the
asynchronous interrupt transfer is polled.
This parameter is required when IsNewTransfer is TRUE.
@param UCBuffer Uncacheable buffer
@param DataLength Indicates the length of data to be received at the
rate specified by PollingInterval from the target
asynchronous interrupt endpoint. This parameter
is only required when IsNewTransfer is TRUE.
@param CallBackFunction The Callback function.This function is called at the
rate specified by PollingInterval.This parameter is
only required when IsNewTransfer is TRUE.
@param Context The context that is passed to the CallBackFunction.
