Help with Avalon 741 cgminer "No devices detected"

[29r]

I'd recommend testing with a different PSU. At this point that seems the most likely thing!

I tried 3 different PSUs but they are probably all from the same batch. I'm concerned whatever hardware issue I have is present in all of the hardware I have.

Thanks again for all your help.

do you live near NJ,USA?

maybe I could meet you and bring a working rasp pi 3 and a working psu and working cables.

if I plug it all in and it works  you know the issue is the psu or one of your cables.

If I plug it all in and it does not work   then the issue is your power outlets.

BTW I would not mine on a gfc outlet.

I could also bring a dmm  to test the power.

only works if you are close

Yeah I would drive to NJ. That's awesome of you to offer to a new member like me.

I am working with a friend on this and he has the equipment. If we don't get this resolved tomorrow, I will send you a pm

We met a local guy who has a 741, tried one of his USB/AUC3 converters and bingo... we're mining. So we got a bad batch of converters... we tried 20 of those little suckers and none of them worked lol.

Thanks everyone for your input on this thread.

Happy mining

You are the second person another purchased a pallet and thirty of the sixty are bad.

Now when I did two group buys of the Avalon 6's we had a few bad and they were brought back to life with high quality brick Feeding   into the rasp pi I linked the solution on this link please wait.

it may be you should look into  one set of  gear describe here  to see if any of the auc's are good.

while this worked with  5 or 6 aucs from the   avalon 6's  whatever is wrong with these new auc 's may not be weak  power.  still worth a shot to try it if you have a lot of avalon's
