I've got a HACTRONIC with a USB connection and the USB driver and software (1.51 - Build 50).
The laptop recognises the HACTRONIC when it’s connected to the USB port, but when I go to Setting > Interface it only shows COM ports (no USB). If I try to connect to the HAC I just get an error message. Anyone come across this before? Software/driver was from CDs provided with updates from the hac4.com website.
