Drivers for USB to serial cables, CAT & programming cables etc.
Recent versions of Windows usually support our USB cables already, however we recommend that for best results you always install the latest drivers for your cable. Here are links direct to the chipset manufacturer's download pages. Driver installation is not usually needed for Linux as the necessary kernel modules are already present.
Our standard cables use CP2102 chips. Our premium cables use FTDI chips and have a paper tag with a red and black FTDI logo. In any case, if you are unsure which cable you have, it won't do any harm to try both drivers.
