function will return the maximum value for the length sum of all

function will return the maximum value for the data length sum of all USB
frames associated with an USB transfer.
In case of control transfers the value returned does not include the
length of the SETUP packet, 8 bytes, which is part of frame zero.
The returned value of this function is always aligned to the maximum
packet size, wMaxPacketSize, of the endpoint which the USB transfer is
bound to.
