Fill ( object buffer, int offset, int count, int timeout, int isoPacketSize ) : void	Fills the transfer with the data to Submit an isochronous transfer.
IncrementTransfer ( int amount ) : bool	Increments the internal counters to the next transfer batch (for transfers greater than UsbEndpointBase.MaxReadWrite)
Reset ( ) : void	Resets the transfer to its orignal state. Prepares a UsbTransfer to be resubmitted.
Submit ( ) : ErrorCode	Submits the transfer. This functions submits the USB transfer and return immediately.
Wait ( int &transferredCount ) : ErrorCode	Wait for the transfer to complete, timeout, or get cancelled.
