Do other 921's on the same controller work? If none work on the controller could be that the controller has not been loaded with the correct firmware. A921 RasPi software is here

None work, the firmware was installed by the Canaan team via teamviewer. I do not recall which version they installed but I will check when I go back to the farm later today.

A thought - did Canaan supply the USB-A to micro USB cable? If not, a very common issue with supplying your own is that many such cables are ONLY for charging and do not support data transfer because all 4 wires in them are used for power. Try using a known good data/charging cable.

Canaan supplied everything this go around. The miners, the psus, the controller, the four auc’s and all the cabling for each.

Could happen but unlikely. I remember a few going out that way with 741's and 8 series I think. I haven't heard of any in a while that went out as duds. Sorry if I missed it. When the controller is powered on, are you able to login and see the GUI? I read this as you have 10 of the miners set up. Did you have them on 2 separate Auc's 5 each? Have you gone back and tried them individually maybe starting at 1 miner and trying different auc/4pin cables?

Yes but unfortunately I am no longer local to you. My farm and I now reside in Michigan. I appreciate the offer though. I did not attempt to run all 10 miners yet. I only got halfway through unpacking/swapping miners before I realized that it was every single one with the problem. I do have another video call with Canaan techs tonight so I will post updates as they happen. It’s currently being powered by usb 3.0 directly connected to my server. I do have a samsung 5v 1amp spare power brick that I can use if you think the server isn’t supplying enough power. The server itself resides on a platinum 1000w ps running maybe 30% load.
When the controller is powered on the GUI is there and I can get into every submenu and make changes. It shows no active connections in its live monitoring and zero speed for fans and hashing. Canaan had me try one by one yesterday on the controller and even had me attempt to power on the miners with no wires connected (except the power supply) all attempts yielded the same result. No signs of life. No way to actually get into them. I was given four auc’s for room for growth after my next purchase after Chinese New Year when their next models are released.

Thanks for helping guys, I ordered that power brick, but in the mean time I am going to try several different ones I have lying around the house. I have one for my home use pi but not sure if it’s the same amperage. I’ll bring that with me and some others. If none work, I’ll try the older firmware. It looks like they did install the January firmware on the controller.
so....it was the psus. Canaan sent me the 911 power supplies not the 921. They are sending me the correct ones via Dhl at no charge.

I had the same issue with January RPi firmware. Using 2018-10-11 with no issues.
duh forgot 921 pulls more juice.
mine pulls 1800 to mine at 19th
With Voltage offset to 0 mine pulls around 2200 with 21 TH/s With -1 it is around 2000 with 19-20 TH/s and with -2 pulls 1800 and 18-19 TH/s
