ProfiLux 3.1T; FW 6.26; S/N: 1605111020
GCC 1.0.84

Installed both FTDI and Prolific USB drivers and I can't connect to the aquarium computer with the supplied USB cable.

I would like to update to F/W 6.27 because I cannot use the Mitras lightbar and hope this update fixes it.

What can I do to fix the USB connection ?
