Soymoji, did you solve your problem?

DO make sure that the USB A-micro cable between the controller and AUC is good for data and is not just a charging cable. Charging cables do not support data transfer (also called 'sync'). Using the wrong cable is a fairly common issue...

Yes, I sure. Other AvalonMiners are working with these cables.



Is there specific firmware for 741?

Is this the right place?

Spooderman, I cannot send a personal message to you. How did you solve your problem with AvalonMiners?

Hello! I have same problems. Units are not detected by controllers and I guess I need to reflash the firmware on the MM (I have already tried to change auc, raspberry, wires and so on). Could you tell me how can I flash the firmware on the MM if the controller is not “seeing” devices? Thank you in advance.
