that can fix the
issue.
If the serial port does not show up when you plug in your Spatial USB device, you may
need to install the drivers from

If you experience a blue screen of death whilst using Spatial Manager, this is typically
a problem associated with older FTDI drivers. To resolve the problem, install the latest
drivers from
http://www.ftdichip.com/Drivers/VCP.htm
When operating Spatial at a very high data rate, data can be lost due to the latency of
the FTDI driver. To resolve this problem the latency of the driver should be reduced by
going to control panel → system → device manager → ports and right click on the USB
serial port, then click properties. In the properties window click the port settings tab
and then the advanced button. You then need to change the latency timer setting to
1ms. Please see the screenshot in Illustration 24.
