Meh. The Chili plug is somewhat appropriate for this thread, but a plug for a pool is not. Please remove it.
Shameless Plug - Selling some Chilis here http://eligius.st/~gateway/products/chili
Good luck selling, did you try eBay those people tend to buy products that will never ROI. At 2.6 coins at current price that thing will never ROI, well it would if difficulty would plummet to only increasing 35% a month and then you would atleast level get .04 coins out of it.
35% forever is unrealistic, there will be some large jumps and then when difficulty gets a certain height the jumps will only be 5-10%
In theory I'll be receiving some super-late-delivery chips here soon if Mr. unresponsive seller has indeed shipped them to me.
I assume I'm too late to have y'all put them onto boards for me, yes?
I'll have enough for 10 or maybe 11 Chilis.
Lucko/Form would seem to be my other option, though keeping everything in the states seems like it would be easier.

Thanks for the answers... did not realize WinUSB vs FTDI was that hot of a topic...
On a Chili note... found that an older Alienware case I had collected a couple years back had a high end 650W PSU in it that still worked... WOOOOOO!
Gutted the thing, tested the PSU for a few hours after shorting the 20 pin (yes I said it was old jeez) and tested all the fans that were in the thing (4 LED riddled 80mms) after cleaning them.
I moved the Chili downstairs to this case and used an old HP netbook to connect and start mining. Downstairs is about 6-8 degrees cooler ambient and WOW... that made a huge difference... now 34 GH/s stable and my main rig is now free again.
I have one more thing to do, had a few old GPUs that had nice heatsink fan combos on them... gutted those cleaned them and had a pal of mine fab some brackets to fit the screw pattern for the Arctic Accelero TT II so I can use them to mount this as a backplate instead of the 9 mini heatsinks I was using. I am hoping this gives me a way to eliminate board flew and more force on the chips, so better cooling, and the addition of a fan underneath venting the heat straight away from the board.
Just waiting on some more TIM now.

update on second batch pcb issue?
The PCB fab has the PCBs back, and spent time today recalibrating their air knife. They're confident going forward, and they should be fixing the boards up on 3rd shift tonight and they should be done tomorrow morning. We'll get them back Friday and they'll be inspected to make doubly sure they're ready to go.In retrospect, it was a mistake to go with HASL instead of ENIG (Electroless Nickel Immersion Gold). ENIG is the better process for pad levelness, but we had good results with HASL before. I was going to make the switch anyway, but it would have added a couple days to the timeline and we wouldn't have gotten started until today or so and I didn't want to do that. It turns out it would have saved time in the end with the poor work since we now won't have boards coming off the line this week anyway.
I am searching for BFGMiner love. I have the newest version 3.5 running but it doesn't identify my miners. Is WinUSB the correct USB driver to use?
No, WinUSB is always the wrong driver for ASICs.Chilis are FTDI: http://ftdichip.com/Drivers/VCP.htm
cgminer requires the WinUSB driver.
bfgminer requires the FTDI serial driver.

Hey MrTeal & ChipGeek,
I have a couple questions that others may have as well.
1. What is the recommended fix for a board that shows up in CG or BFG but just never hashes? LEDs 1-4 are solid and then 7 & 8 may blink or remain solid. Device shows up as enabled and send temp reading but never hashes.
2. What is the recommended fix for a board that consistently starts showing a hash rate of 200GH+ and its all hardware errors?
3. Is there any known method to override the throttling at current temp settings other than a firmware change?
Thanks again for the great boards!
1. Update to the newest firmware. This is a known issue with the new Rev B ASIC chips that we did not see in the older Rev A samples.I have a couple questions that others may have as well.

2. Rebooting the board will fix the problem if it is what I think it is. If rebooting never helps, then send MrTeal a PM for directions on what to do next. I will have a firmware fix for this but have been busy with real life stuff and getting batch 2 built.
3. No other than keep the board cooler with a better heatsink or TIM. We plan to have a firmware update to assist you in having more control over this. (See excuses in #2)
Please remember, we're a very small team - not a swarm of locusts.

But we were talking about BFGMiner...
curious why this is "wrong" with cgminer? Is there a performance gain using FTDI with BFG?
Also because cgminer's replacement driver (only built on top of WinUSB) doesn't provide the standard VCOM interfaces the chip is supposed to have.

Interesting. I am using WinUSB CGMINER. That would explain why BFG miner isn't working though.
These is new firmware?
How I install it?
No, it's the same firmware that shipped on the second half of the first batch.How I install it?
Open ChiliFlash, and select the Chili that needs to be flashed from the drop down menu. Browse the the ChiliFW14c.hex hex file, and then hit program. The LEDs on the board should binary count quickly, and when it's done it will prompt to power cycle the unit and the LEDs should flash outer 4 then inner 4 until you do.
Is there a way to determine a board's current firmware version with a serial console? I don't know if I already have 14c, and they're connected to a linux pc. I tried the ZCX command but the output doesn't appear to include the firmware version.

Probably the added airflow over the back of the regulator area.
