+ Make sure that your OS has the required drivers installed
+
+ On Linux this means you need to have the correct kernel
+ module loaded. Most distributions will do this automatically
+ for you.
+
+ On Windows, the OS should offer to download the correct
+ driver when you connect to the USB port.
+
+ On a Mac you at times have to manually hunt for the correct
+ driver. For example the correct driver for the Mares Puck
+ devices can be found as Mac_OSX_VCP_Driver.zip at
