If the device sends more than 256bytes of data at a time VirtualBox seems to buffer it into 256byte piece, and only sends a piece when there is a communication from the OS to the device. I'm running VirtualBox on a Windows XP host, with an Ubuntu Guest." defect closed other VirtualBox 3.0.8 duplicate serial Linux Windows
