Good day everyone, I just wanted to post a State of the Hanns message...

Since I last posted, in order to rule out the TP-Link as the issue, we wired the modules from Hanns (broken Avalon) into Ada (working Avlaon).

Using the USB cord that would normally go from Ada's Control Unit to Ada's TP-Link, we instead plugged into Hanns' TP-Link.

The result was that Ada was able to mine through Hanns' TP-Link totally normally (even showed up with Hanns' credentials in the pool).  So this would seem to mean that the problem isn't with the TP-Link itself.  Next I was thinking of moving the Control Unit from Hanns and swapping into Ada to confirm that the issue is with the Control Unit. 

There is a blue and white ribbon cable running from the CU to the PDU and I wanted to confirm that it is able to be removed from the Control Unit?

I'll also be trying a few of the software fixes mentioned here, but since we were able to mine with the card using the TP-Link from the broken machine, it would seem that it isn't a software issue related to CGMiner or the router itself.

One final thing, I was in contact with Christian over at Bitmine.  He has been very helpful and I can't say enough good things about their customer service for being so prompt and honest in their dealings.  What I have now ascertained is that the Control Units that Bitmine is able to supply don't work with the PDU for Batch 3 Avalons. 

Does anyone know more about the difference between the Batch 3 and previous batches PDU's and where one might obtain such a rare and valuable gem? 

Anyways, hopefully that helps someone along to claiming the 1BTC bounty that I am currently offering for anyone who can provide a fix for this ailing machine.
