OK trying to set up my first set of 741s (have experience with s9 and e9 miners) and I'm having issues having the controller recognize any modules. I am down to troubleshooting one module with the controller to see what I can do.

Using a 2A usb plug for the controller.
Firmware 20170603
1200W HP server PSU @ 240V

AUC3 converter is blue with green light....
I've tried a couple different converters, cables and usb cables to no avail.... any help would be appreciated.
