For the correct operation of the USB connection, you should install the proper
drivers. For this, you only need to access to the information of the proper model
in:
http://www.ftdichip.com/Drivers/VCP.htm
From here, you can download the required files and complete their correct
installation.
Note: Installation in the driver Host of the SD700SP USB, USB device of the SD700SP will be detected by operating
systems XP and 2000, it is only necessary to indicate the driver at the time of the installation. In case of operating
systems before W98 / Me, execute a search of new Hardware in the device administrator, and complete the
installation by indicating the drivers when the computer requires them.
