For the correct operation of the USB connection, it is necessary to install
the proper drivers. To this, simply access to the information of the
appropriate model in:
http://www.ftdichip.com/Drivers/VCP.htm
From this site you can download the required files and complete their
correct installation.
Note: For the installation of the driver in the Host of the SD750 Kompakt USB, it is only necessary to indicate the driver
at the time of the installation. The USB device will be detected by the operating systems XP or later versions. 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.
