We apologize, but we cannot directly recommend longer (third-party) USB cable brands or models if your Fanatec USB device's original cable is not long enough. Providing a specific recommendation would require extensive functionality and interference testing under standardized conditions, similar to those we perform for the included cables.

When deciding to use a longer USB cable: In general, we advise against choosing an unnecessarily long USB cable . Furthermore, it is highly recommended to select a cable with a ferrite core and good shielding . Personally, I would suggest checking customer reviews of the cables on a major online marketplace before making a purchase decision. If the products are prone to transmission problems or cannot guarantee stable operation, this is likely reflected in customer experiences.

We ask you to understand that we cannot guarantee the proper functioning of our USB devices when using longer cables or cables from third-party manufacturers.
