The driver that came with my cable was lost so I downloaded CUM-360.zip from the Maxxtro site it didn't seem to work quite right. Found the original and it works. Unzip files onto a floppy and name floppy volume DISK1. Then insert your cable, when asked for driver browse to floppy and then it will install.
The following files are found inside the driver download file.
