The odroid u3 is a good alternative http://hardkernel.com/main/products/prdt_info.php  I ditched all my pi for them due to usb issues

How are your waterblocks performing ?
If I remember correctly you have got XSPC waterblock. I'm using cheap china stuff and would like to buy new ones.

It's running fine for me on the 5-14 Debian firmware.  Are you running an Angstrom release?

Edit: Reading comprehension - hotplug.  I tend to power-cycle to reboot miners so I forgot that the habanero must be plugged from bootup.

Hey guys,

Sorry for the delay on details about another batch. There's a couple things involved with this. The first is Batch 2 availability; this run is completely sold out of boards that passed at speed, but we still have boards left. Some of those will be outright write-offs, but some just have issues like there's a solder bridge between pins or have a resistor that got placed off kilter, and they just need to have that touched up and they're good to go. Right now we're waiting to see how many of those we'll have available.
On top of that, we have a few boards with one bad die, or that some reason don't pass test at stock speed and voltage, but that do hash otherwise. Those need to be retested and we need to figure out what to do with them, whether they get sold at a discount, we keep them, etc.

On batch 3, it's still up in the air a little bit unfortunately. I would say it's pretty likely at this point, but we're just waiting on confirmation of a couple big orders that would make is feasible.
It's a bit of a chicken and egg scenario, we need a certain quantity to justify a batch, but we don't want to do presales through the website without knowing for sure that the batch is 100% or having to delay it waiting for more people since that's not fair to any of you. Getting a couple big orders signed up makes it possible to pull the trigger without us having to lay out mid six figures of our own money to pre-buy everything (which we wouldn't have anyway), or put ourselves in a situation where we might not be able to provide what we promised within a reasonable period of time. I hope to know more here in the next day or two.

it's my first time mining for real.  I've tinkered on a pc before but that's not real is it?

Edit: I was told that I wouldn't be able to blow it up without a fan since it has thermal protection.  Currently running with a temporary air heat sink at 75MHz with a temperature of 99C.  Is that bad too?

Tell me about it.  But in my defense, there is absolutely no instructions available for this unit on peppermintmining.com.  I had to figure everything out by other means and am surely lacking information.

WOW... before you blow yours up... just send it to me... 4 pin... then not using all 4 PCIe plugs... and running it without a cooler? You're gonna break this thing if you don't just wait for your gear... that it has not died already is a testament to Dr Teal + teams excellent work.

I'm okay now, it wasn't clear to me that power was required on all four plugs.  (at least it is in my case)  USB errors are for the most part gone.

My cooler has yet to arrive and I'm reaching thermal overload rather quickly even with "--hfa-hash-clock 100".
I'm assuming this is normal behavior without a cooler on board.  I'm going to see how much hashing I can achieve with my cpu air cooler resting on the die with the fan on it.  

In the spirit of "optimization", I have a board that we swapped out for a customer that had a die down. I'm going to send it back to the assembly house to get it xrayed to see if there is a cracked ball under the ASIC for that die, but before I did I wanted to see how far I could push just 3 dies where in theory thermals should be less of an issue.

The interesting thing is that each PCIe plug is its own rail, with its own 6 phase VRM feeding one die on its own plane. It's not like the VRM for the phase that's down is helping out; it's not even turned on. The only difference between 3 dies as 1050MHz and 4 dies at 1050Mhz is getting the heat away.
I really think I need to buy some of that Cool Labs liquid metal TIM (despite the risks) and hook up a real water block to the municipal water supply, just to see if I can get 1050 on a fully working chip.

I had a similar error, but I cant remember if it was the exact same. My issue was a missing WinUSB driver. I installed the missing driver using zadig (http://zadig.akeo.ie/), and haven't had any issues since.
